Abstract:
A color filter (19) used in a transmissive color liquid crystal display panel of a color liquid crystal display (LCD) apparatus. This color filter (19) is constituted by a tristimulus color filter for wavelength-selecting and transmitting red light, green light and blue light. Mixing of blue color and red color is prohibited by not having the transmission wavelength band of the red filter CFR overlaid substantially on the transmission wavelength band of the blue filter CFB.
