Abstract
In a three-dimensional image display apparatus provided with a shading mask with a minute aperture array in front of a color display device, the minute apertures are provided with color filters, a setting is provided so that the visual angles between the respective centers of the red-light transmitting part, green-light transmitting part, and blue-light transmitting part of the color filters become equal, in an identical parallax image pixel region, to the visual angles between the respective centers of the red, green, and blue sub-pixels of the color display device, the respective red, green, and blue sub-pixels are made so as to be always displayed in a lighted condition at a fixed area ratio, thus color reproduction wherein brightness ratio of the three primary colors in respective parallax image pixels is maintained at an appointed value is carried out.
