PROBLEM TO BE SOLVED: To miniaturize a color-generating device. SOLUTION: The color-generating device comprises at least three kinds of wavelength selective reflection elements 4r, 4b, 4g arranged in parallel with each other and reflecting three kinds of wavelength bands and a plurality of elements 1, 2, 3 for rotating the planes of polarization arranged on respective incident sides of the wavelength selective reflection element 4r, 4b, 4g. |
