description The present invention is to provide a liquid crystal device having color filters, wherein a color changing substance for changing a portion of incident light into the light within a specific wavelength domain is provided to at least one of the said color filter, and the present invention also provides the filtering substance for penetrating the light in the specific wavelength domain. Thus, the present invention can prevent the reduction of color purity of the light emitted from the liquid crystal display and improve the light efficiency.
