A projection type display device is provided which is compact and allows an image to be displayed in appropriate colors. A color wheel is disposed in an area interposed between a light entering a total reflection mirror and a light reflected by the mirror. This makes the device compact compared to a case where the color wheel is placed in a region outside the light. Further, the color wheel is shaped like a disk divided into a plurality of color filter sections of different colors. The color wheel is irradiated with a light converged in such a shape as to pass through only a single color filter section. Consequently, the light is properly separated to allow an image to be displayed in appropriate colors.
