A liquid crystal display comprising a backlight module and a liquid crystal display panel is provided. The backlight module comprises a white point source that emits a spectrum of light comprising three peaks. The liquid crystal display panel comprises a liquid crystal layer disposed between a color filter substrate, which comprises a blue filter, a green filter and a red filter, and an opposite substrate. The color filter substrate and the backlight module satisfy the following formulas: ∑ 555 605 BL ( λ ) × CF Red ( λ ) × &Dgr;λ ≤ 6.0 ; ( 1 ) ∑ 580 630 BL ( λ ) × CF Green ( λ ) × &Dgr;λ ≤ 3.5 ; ( 2 ) ∑ 505 580 BL ( λ ) × CF Blue ( λ ) × &Dgr;λ ≤ 3.5 . ( 3 ) Herein, the backlight module has the maximum luminance in one wavelength, with the maximum luminance being set at 1.0. BL (λ) represents the normalized luminance spectrum at each wavelength. CFBlue(λ), CFGreen(λ) and CFRed(λ) represent the transmittance of light at each wavelength passing through the blue filter, the green filter, and the red filter respectively. &Dgr;λ is the wavelength interval.
