    摘要： In a display apparatus according to an embodiment, a variable diffuser film is disposed between a backlight unit generating light and a display panel displaying an image. The variable diffuser film transmits or scatters the light from the backlight unit in response to an electrical signal to control a viewing angle. 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.

    摘要： Disclosed are a prism sheet and a liquid crystal display having the same. The prism sheet includes a base and a plurality of prism mountains. The base includes a front surface and a rear surface facing the front surface. The prism mountains are integrally formed with the base on the rear surface of the base. At least one prism mountain includes a plurality of light incidence surfaces and a reflective surface. The light incidence surfaces receive light. The reflective surface is adjacent to one of the light incidence surfaces to reflect the light. A vertical angle of the prism mountains formed between the light incidence surface adjacent to the reflective surface and the reflective surface, is in a range of about 70° to about 100°.
