ABSTRACT:
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.
