LIQUID CRYSTAL DISPLAY DEVICE

摘要

An LCD(Liquid Crystal Display) device is provided to obtain the simplified device structure without the resolution lowering by supplying a veil-view function through a PDLC(Polymer Dispersed Liquid Crystal) sheet. A light source part(100) is located at the back of the LCD panel(200). A reversible diffusion sheet(400) is located in front of the light source part, and adjusts the light diffusion according to the voltage application. A barrier sheet(300) is located in front of the liquid crystal display panel, and transmits the light having vertical direction, and cuts the light of each prescribed direction. The barrier sheet comprises the multiple sub-sheets arranged in the vertical direction. Each sub-sheet is arranged in the vertical direction of the panel. The reversible diffusion sheet comprises a polymer layer and a liquid crystal molecule distributed in the polymer layer, and transmits the light in the vertical direction by arranging the molecule uniformly in case of voltage application.
