Liquid Crystal Display

摘要

A liquid crystal display comprises: a light source unit (20); a light converting unit (40) for receiving light from the light source unit (20) and converting a polarization property and a brightness distribution of the received light; a screen (71) for receiving the converted light from the light converting unit (41) and improving a frontal brightness of the converted light; and a liquid crystal display panel (10) disposed in front of the screen (71). Thus, the present invention provides a liquid crystal display having high light efficiency without using an expensive optical film.
