A projection device includes an illumination system, a light splitting and combining element, at least two light valves and an image-forming lens. An illumination beam from the illumination system includes a first color light and a second color light. The light splitting and combining element allows the first color light to pass through and reflects the second color light. The two light valves are respectively disposed on transmission paths of the first and the second color light from the light splitting and combining element, and respectively convert the first color light and the second color light into a first and a second color image light. The image-forming lens receives the first and the second color image light to generate a projection beam, wherein the first color image light passes through and the second color image light is reflected by the light splitting and combining element to the image-forming lens.
