发明名称 Projection type display apparatus with color optimized anti-reflection films
摘要 In a reflection type liquid crystal projector, anti-reflection film optimized for the corresponding color (wavelength band) is formed on each of the light passing surfaces of a cross dichroic prism which are opposed to liquid crystal panels of respective colors and the reflectance of each anti-reflection film is made sufficiently small to thereby enhance the contrast of a colored image projected onto a screen by a projection lens.
