LIQUID CRYSTAL DISPLAY

摘要

An LCD is provided to realize a narrow viewing angle by reducing the emitting angle of light in an area on a pixel area by a Fresnel lens and a prism unit, thereby adjusting a viewing angle according to user's request. An LCD(Liquid Crystal Display) comprises a pixel electrode unit, a light source unit, and a light concentrating unit. The pixel electrode unit includes a first pixel electrode unit(192) and a second pixel electrode unit. The light source unit provides light to the pixel electrode unit. The light concentrating unit concentrates light emitted from one of the first pixel electrode unit and the second pixel electrode unit to a predetermined direction.
