Abstract:
A color liquid crystal display device includes a liquid crystal display element and a backlight unit. The liquid crystal display element includes a color filter having a red filter segment, a green filter segment, and a blue filter segment. The red filter segment is prepared from a red photosensitive resin composition which includes a pigment combination, an alkali-soluble resin, a compound having an ethylenic group, and a photoinitiator. The pigment combination includes an azo-based red pigment and an anthraquinone-based red pigment. A weight ratio of the azo-based red pigment to the anthraquinone-based red pigment ranges from 20/80 to 80/20. The backlight unit is coupled to the liquid crystal display element and has a color temperature ranging from 6,000 K to 20,000 K.
