The variable diffuser film is disposed between the first and second transparent layers and includes a polymer layer in which liquid crystal molecules transmitting or scattering the light according to the electrical signal are dispersed. The polymer layer has a thickness of about 3 micrometers to about 15 micrometers, and the liquid crystal molecules have an anisotropic refractive index (Δn) of about 0.15 to about 0.25. In one aspect, the display apparatus may automatically switch a narrow viewing angle mode and a wide viewing angle mode, thereby reducing power consumption necessary to switch the narrow and wide viewing angle modes. | 10-21-2010 |
