There are provided color liquid crystal display devices with high color purity of NTSC percentage of at least 80%. A color liquid crystal display device comprises a combination of light shutters utilizing a liquid crystal 7, a color filter 9 having color elements of at least three colors of red, green and blue corresponding to the light shutters, and a backlight 1, 2 for transmission illumination. Under the following definitions: TG(nulln) represents a spectral transmittance at a wavelength nulln nm (a wavelength at every 5 nm in the visible light region of from 380 to 780 nm) by a green pixel of the color filter 9; and I(nulln) a relative emission intensity, normalized by a total emission intensity, at a wavelength nulln nm from the backlight, these satisfy the following conditions (1) to (3): (1) at one wavelength in 500 nm 0.01; (2) in a wavelength region of 610 nm
