PROBLEM TO BE SOLVED: To constitute an efficient display panel whose pixel pitch is fine by alternately arraying the plural light beams of three colors R, G and B as the illumination light and respectively illuminating the plural adjacent pixels of the display panel with the light beams of identical color. SOLUTION: Dichroic mirrors Rm, Gm and Bm reflecting the light beams having R, G and B wavelength regions are arranged behind a UVIR cut filter 7 at different inclinations. Light beams 9 made incident along an optical axis L are reflected by the respective mirrors Rm, Gm and Bm and arrive at a 1st lens array 4 arranged behind with optical axes LR, LG and LB having different angles. Then, the images of the light beams 9 of R, G and B, arriving at the array 4 from different directions, are formed for each cell 4a on the individual cell 6a of a 2nd lens array 6 arranged slightly behind each cell 40. Then, the plural pixels 16b of the display panel 16 are illuminated by each color with the light beams color-separated into R, G and B by the mirrors Rm, Gm and Bm and the 1st and the 2nd arrays 4 and 6. |
