<p><P>PROBLEM TO BE SOLVED: To provide an image projector which has such constitution that optical components including image display elements are adhered closely to one another, then, can be made compact. <P>SOLUTION: A light pipe 2B, an incident-side polarizer 5B, the image display element 7B and an exit-side polarizer 9B are arranged on at least one optical path among optical paths of the lights emitted from a plurality of color light sources 1A to 1C. Light pipes 1A and 1C, prisms 3A and 3C, incident-side polarizers 5A and 5C, image display elements 7A and 7C and exit-side polarizers 9A and 9C are arranged on other optical paths. By separately fixing the prisms 3A and 3C and a color compositing part 21 to pedestals, the light incident surfaces of the image display elements 5A and 5C joined to the color compositing part 21 through the exit-side polarizers are adhered closely to the light exit surfaces of the incident-side polarizers 5A and 5C integrally molded with the light exit surfaces of the prisms 3A and 3C. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
