Patent ID: 7639323

Claim:
A liquid crystal display (LCD), comprising: a backlight module having at least one white light source, wherein BL 1 and BL 2 respectively represent maximum brightness peaks of a normalized emission spectrum of the backlight module at a wavelength between 500 nm and 520 nm and between 445 nm and 465 nm, and 0.91≦BL 1 /BL 2 ≦0.99; a liquid crystal display panel disposed above the backlight module and having a plurality of substrates and a liquid crystal layer located between the substrates, wherein one of the substrates has a red filter layer, a green filter layer, and a blue filter layer, and the red filter layer, the green filter layer, and the blue filter layer satisfy the following relation expressions: R x ≧0.655, G x ≧0.275, B y ≦0.075, wherein R x is defined as x coordinate value of the red filter layer in CIE 1931 chromaticity coordinate diagram under a C light source, G x is defined as x coordinate value of the green filter layer in CIE 1931 chromaticity coordinate diagram under the C light source, and B y is defined as y coordinate value of the blue filter layer in CIE 1931 chromaticity coordinate diagram under the C light source.
