Abstract

PURPOSE:To increase apparent transmittivity to about 100% and to improve color reproducibility by making refractivity and the thickness of thin films between stripes meet prescribed requirements by forming a semiconductor stripe filters on a light-transmissive substrate with the 1st light-transmissive thin film interposing and then by forming the 2nd light-transmissive thin film on it. CONSTITUTION:A color separation stripe filter consists of a light-transmissive substrate 1 having refractivity ns, a light-transmissive thin film 2 having refractivity nT1, a semiconductor stripe filter 3 having refractivity nF, a light-transmissive thin film 4 having refractivity nT2, and a light-transmissive dielectric layer 5 having refractivity nD. Their film thicknesses are so determined that while ns<=nT1<=nF and nD<=nT2<=nF, spectral characteristics of the light-transmissive thin films formed in gaps between strips have an lambda0/4 (lambda0; reference wavelength) reflection peak in the basic absorption range of the semiconductor stripe filter or an lambda0/2 transmission peak in the range of wavelength longer than 700nm. Thus, the apparent transmittivity increases up to about 100% and the color reproducibility is improved.
