摘要： 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 ) × Δλ ≤ 6.0 ; ( 1 ) ∑ 580 630 ⁢ ⁢ BL ⁡ ( λ ) × CF Green ⁡ ( λ ) × Δλ ≤ 3.5 ; ( 2 ) ∑ 505 580 ⁢ ⁢ BL ⁡ ( λ ) × CF Blue ⁡ ( λ ) × Δλ ≤ 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. Δλ is the wavelength interval.

摘要： A display device and a display panel and a color filter thereof are provided. The color filter includes a transparent substrate, at least a red filter film, at least a green filter film, at least a plurality of blue filter film and at least a white filter film. The red filter films, the green filter films, the blue filter films and the white filter films are disposed on the transparent substrate. The blue filter films have a first largest transmittance when a light with first wavelength transmits it. The green filter films have a second largest transmittance when a light with second wavelength transmits it. The white filter films have a third largest transmittance when a light with third wavelength transmits it. The third largest transmittance is larger than the first largest transmittance and the second largest transmittance. The third wavelength is between the first wavelength and the second wavelength. Therefore, the images displayed by the display device with the color filter may have accurate color-level and high brightness.
