ABSTRACT:
A liquid crystal display (LCD) including a backlight module and a liquid crystal display panel is provided. The backlight module has at least one white light source. BL1and BL2respectively represent maximum brightness peaks of a normalized emission spectrum of the backlight module at a wavelength between 500 nm to 520 nm and between 445 nm to 465 nm, in which 0.91≦BL1/BL2≦0.99. The liquid crystal display panel is disposed above the backlight module, and has a plurality of substrates and one liquid crystal layer located between them. One of substrates has a red filter layer, a green filter layer, and a blue filter layer, and the coordinate values of the red filter layer, the green filter layer, and the blue filter layer in CIE 1931 chromaticity diagram satisfy predetermined relation expressions.
