Abstract:
A liquid crystal display including a backlight unit and a liquid crystal display panel is provided. A spectrum of the backlight unit has relative maximum brightness peaks at wavelength between 460 nm to 480 nm, between 505 nm to 525 nm, and between 610 nm to 630 nm. The liquid crystal display panel is disposed above the backlight unit. The liquid crystal display panel has a red color filter layer (Rx, Ry, RY), a green color filter layer (Gx, Gy, GY), a blue color filter layer (Bx, By, BY) and a yellow color filter layer (Yx, Yy, YY), wherein under the backlight source, the red color filter layer, the green color filter layer, the blue color filter layer and the yellow color filter layer satisfy following conditions: Rx≧0.654; Ry≦0.330; Gx≦0.253; Gy≧0.605; Bx≦0.136; By≦0.146; Yx≦0.408; Yy≦0.534; 0.83≦RY/GY≦0.87; 0.86≦GY/BY≦0.92; 0.83≦BY/YY≦0.87 and 1.5≦YY/RY≦1.55.
