20080231783 | REFLECTIVE-TRANSMISSIVE TYPE LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR FABRICATING THE SAME - A reflective-transmissive type liquid crystal display device and a method for fabricating the reflective-transmissive type liquid crystal display device are provided. The reflective-transmissive type liquid crystal display device includes a pixel electrode having a transparent electrode for displaying information in a dark place where light is insufficiently provided, a reflective electrode for displaying information in a place where light is sufficiently provided, and an orientation film having an orientation groove provided on an upper surface of the pixel electrode, the direction of the orientation groove being varied depending on a shape of the reflective electrode. The reflective-transmissive type liquid crystal display device prevents the generation of an afterimage, which is generated when a response speed of liquid crystal is lowered due to the impurities or ions stacked at a boundary of the reflective electrode and the transparent electrode, thereby improving quality of display. | 09-25-2008 |
20090162958 | ARRAY SUBSTRATE, METHOD OF MANUFACTURING THE SAME AND LIQUID CRYSTAL DISPLAY APPARATUS HAVING THE SAME - An array substrate includes a transparent substrate, an organic insulation layer, a pixel electrode, a reflective layer, a light blocking pattern and a switching part. The transparent substrate includes a reflective window that reflects an ambient light and a transmissive window that transmits an artificial light. The organic insulation layer disposed over the transparent substrate becomes thinner gradually at a boundary between the transmissive window and the reflective window. The pixel electrode is formed in the transmissive region. The reflective layer is disposed over the organic insulation layer of the reflective window. The light blocking pattern is disposed at the boundary between the transmissive and reflective windows to prevent a light leakage. The switching part is electrically connected to the pixel electrode to apply an image signal to the pixel electrode. Therefore, a light leakage occurring at boundary is prevented by the light blocking pattern. | 06-25-2009 |
20090213310 | MANUFACTURING METHOD OF TRANSFLECTIVE LCD AND TRANSFLECTIVE LCD THEREOF - A manufacturing method of a transflective LCD comprising forming a multiple layer on a substrate by depositing transparent electrode layer and a gate metal layer sequentially, forming a gate line, a gate electrode, a gate pad forming part and a data pad forming part by patterning the multiple layer, forming a gate insulating layer, forming a semiconductor layer, forming a data line, a source electrode and a drain electrode, forming a passivation layer and an organic insulating layer and forming a gate pad and a data pad by providing contact holes exposing the transparent electrode layer on the gate pad forming part and the data pad forming part, respectively. | 08-27-2009 |
20090273736 | Liquid Display Device and Method for Fabricating the Same - A liquid crystal display device includes a first substrate, a second substrate and a liquid crystal interposed between said first and second substrates. The first substrate includes a plurality of thin film transistors, an organic insulating layer, said organic insulating layer including a contact hole exposing an output of each of said thin film transistors, a plurality of first electrodes disposed on said organic insulating layer and each connected with said output, and a viewing-angle varying section between the first electrodes, the viewing-angle varying section including a curved surface of a half-cylindrical shape and protruding from the organic insulating layer. The viewing-angle varying section has a symmetrical shape, and the portions of said first electrode disposed at each side of said viewing-angle varying section asymmetrically extend onto the curved surface of said viewing-angle varying section, to thereby change the reflection factor depending on an observation angle. | 11-05-2009 |
20100045916 | UPPER SUBSTRATE AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE SAME - A liquid crystal display apparatus includes a lower substrate, an upper substrate and a liquid crystal layer interposed between the lower substrate and the upper substrate. The lower substrate includes a display part for displaying image and a driving part for providing the display part with a driving signal. The upper substrate includes a common electrode and an insulating member that electrically insulates the common electrode from the driving part. The insulating member has a lower dielectric constant than the liquid crystal layer. Thus, a parasitic capacitance between the driving part and the common electrode is reduced to prevent malfunction of the driving part, and a display quality is enhanced | 02-25-2010 |
20100165270 | COLOR FILTERING DEVICE FOR IMPROVED BRIGHTNESS - A color filtering member for improving the brightness of a display device is presented. The color filtering member includes colored regions (e.g., regions with RBG color filters) and black-and-white regions for transmitting white light. The black-and-white regions may be colorless gaps between adjacent colored regions. Multiple planarizing layers may be deposited on the colored regions and the black-and-white regions to form a surface that is sufficiently even. The color filtering member may include an intercepting region that extends between neighboring colored regions. The position of the intercepting region is not centered between the two colored regions that it separates. Rather, the intercepting region is shifted in the direction of rubbing (in the direction of liquid crystal alignment) to more effectively cover the regions where light leakage occurs. This color filtering member may be combined with an array member and a liquid crystal layer to form a display device. | 07-01-2010 |
20110134376 | ACTIVE MATRIX DRIVING DISPLAY DEVICE AND IMAGE DISPLAYING METHOD USING THE SAME - LCD device includes two substrates, a first and second color filters, two liquid crystal layers. The first color filters are formed on portions of the second substrate corresponding to border area The second color filters are formed on portions of the second substrate corresponding to the display area except the border area. A first liquid crystal layer between the first and the second substrate is comprised in border area, and a zero electric field is formed on the first liquid crystal layer so as to completely transmit light incident into the first liquid crystal layer therethrough. A borderline having various colors can be displayed by forming various patterns of color filters having various colors on portions of the second substrate corresponding to the border area under normally white mode, thereby producing picture frame effect while images are displayed on the screen. | 06-09-2011 |
