Abstract
A color filter includes at least one blue color resist including a blue pigment and a violet dye, in which the ratio of the blue pigment to the blue color resist is in a range from 84.2% to 88.8% by weight, the ratio of the violet dye to the blue color resist is in a range from 11.2% to 15.8% by weight, so that a blue light with a y coordinate in a range from 0.045 to 0.051 in the CIE chromaticity diagram is generated when light passes through the blue color resist. Furthermore, a liquid crystal display device employing the color filter is also disclosed herein.
