  • Patent number: 9470925
    Abstract: A liquid crystal display device includes a liquid crystal panel and a collimated exit light backlight module. The liquid crystal panel includes a CF substrate, an array substrate, and a liquid crystal layer. The CF substrate has an upper surface on which an upper polarizer film is arranged. The array substrate has a lower surface on which a lower polarizer film is arranged. The upper polarizer film includes a view angle diffusion film arranged thereon. The collimated exit light backlight module includes two backlight sources, a metallic grating reflector plate, a wire grid polarizer, and an optic film assembly. The two backlight sources, the metallic grating reflector plate, and the wire grid polarizer collectively define a light guide chamber. 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.
