PROBLEM TO BE SOLVED: To provide a head-mounted type color video projector, a color hologram optical element, and a method for manufacturing a color hologram optical element which are small in size and capable of securing necessary see-through properties. SOLUTION: Light from a light source 1 enters a color hologram optical element 4 via a waveguide 11. Light from each of the element color holograms 40R, 40G, 40B corresponding to RGB of the color hologram optical element 4 passes through pixels 7R, 7G, 7B corresponding to RGB of the liquid crystal display element 5, A color image is projected on the retina 10. |
