Abstract:
1. A photoluminescence LCD (liquid crystal display) comprising: a light source emitting polarized light; a light control unit including a liquid crystal layer having a plurality of pixel regions and modulating a polarization direction of the polarized light individually with respect to each of the pixel regions; a polarizer transmitting the modulated light only when the polarized light has a polarization direction; a photoluminescence layer excited by the light transmitted through the polarizer and emitting excitation light by photoluminescence; and a light guide plate being on a rear surface of a light control unit to guide the polarized light emitted from the light source to the light control unit while maintaining the polarization direction of the polarized light, wherein the light source is a semiconductor laser diode, and the light source is on a lateral side of the light control unit.
