A color filter has red, green, and blue filter segment pixels on a substrate. When a pseudo-white LED having a particular spectral characteristic is used as a light source, the red, green, blue filter segment and the chromaticity points in the CIE table color system of the red, green, blue filter segments are (xR, yR), (xG, yG), (xB, yB), respectively: the area of the triangle defined by these three points on the x-y chromaticity diagram are 72% or above of the area of a reference triangle defined by the three points: red (0.67, 0.33), green (0.21, 0.71), blue (0.14, 0.08); the color temperature is not lower than 6000K; and the filter segment of the red, green, blue filter segments have a film thickness not greater than 3.3 μm. The liquid crystal display device includes the color filters and the pseudo-white LED. |
