Abstract
In a liquid crystal display device comprising color filters therein, the present invention provides a color-converting material in at least one of the color filters which converts a part of an incident light of the at least one of the color filters into a light in a specific wavalength range together with a filter material passing the light in the specific wavelength range, so as to prevent deterioration of color purity of the light emitted thereby and to improve efficiency of optical utilization therein.
