摘要：
In a color liquid crystal display panel of a CF-on-TFT structure having a black matrix and a color filter formed on a TFT substrate, reflected light is reduced by selecting and controlling a gap (d) of the CF-on-TFT panel and refractive index anisotropy (&Dgr;d) of a liquid crystal material by exploiting the presence of wavelength dependency between retardation (&Dgr;nd) and light transmittance so as to shift the wavelength of reflected light of external light from a pixel electrode ITO to a shorter wavelength side.
