LIQUID CRYSTAL DISPLAY DEVICE

摘要

The present invention provides a liquid crystal display device, which includes a liquid crystal panel (1) and a collimated exit light backlight module (3). The liquid crystal panel (1) includes a CF substrate (11), an array substrate (13), and a liquid crystal layer (12). The CF substrate (11) has an upper surface on which an upper polarizer film (15) is arranged. The array substrate (13) has a lower surface on which a lower polarizer film (17) is arranged. The collimated exit light backlight module (3) includes a light guide plate (31), at least one backlight source (33), an optic film assembly (35), and a bottom reflector plate (37). The upper polarizer film (15) includes a view angle diffusion film (19) arranged thereon. The optic film assembly (35) includes a birefringent polarizer (351). The birefringent polarizer (351) separates polarized lights. The liquid crystal display device greatly improves light transmittance and light extraction efficiency and also effectively overcomes the issue of color deviation at a large view angle.

主权项

1. A liquid crystal display device, comprising: a liquid crystal panel and a collimated exit light backlight module that provides a light source to the liquid crystal panel, the liquid crystal panel comprising a color filter (CF) substrate, an array substrate that is arranged opposite to the CF substrate, and a liquid crystal layer that is filled between the CF substrate and the array substrate, the CF substrate having a surface that is distant from the liquid crystal layer and comprises an upper polarizer film arranged thereon, the array substrate having a lower surface that is distant from the liquid crystal layer and comprises a lower polarizer film arranged thereon, the collimated exit light backlight module comprising a light guide plate, at least one backlight source arranged at one side of the light guide plate, an optic film assembly arranged above the light guide plate, and a bottom reflector plate arranged below the light guide plate, the upper polarizer film comprising a view angle diffusion film arranged thereon, the optic film assembly comprising a birefringent polarizer, the birefringent polarizer separating polarized lights.
