发明名称 PROJECTOR
摘要 <P>PROBLEM TO BE SOLVED: To provide a projected image which is bright and in which the occurrence of color unevenness and coloration is suppressed by improving the light use efficiency of projection light by taking into consideration the optical characteristics of a reflection mirror furnished in a projector. <P>SOLUTION: The projector projecting images is equipped with a screen, a projection section which projects the projection light indicating the image reproduced by a plurality of color light, and an optical path changing section which directs the projection light projected from the projection section toward the screen. The projection light is composed of approximately linearly polarized light. The optical path changing section has a main reflection mirror which reflects the incident projection light toward the screen. The main reflection mirror is composed of a film-like mirror formed by coating the top of a resin film formed by stretching a resin material with a metallic film. The stretching direction of the resin film is so arranged as to be aligned with the direction perpendicular to the incident plane of the main reflection mirror. <P>COPYRIGHT: (C)2006,JPO&NCIPI
