A reflective liquid crystal projector is miniaturized to sizes to be incorporated in small devices such as a portable telephone terminal. Red, green and blue laser beams (1R, 1G, 1B) are diffused by diffractive optical elements (21R, 21G, 21B) so that each of the beams is entirely diffused over the display area of a reflective liquid crystal panel (40) and enters a corresponding pixel of a liquid crystal layer (41). The diffused laser beams (2R, 2G, 2B) are inputted to the reflective liquid crystal panel (40) through a field lens (31) and a polarizing beam splitter (33). Pixels of red, green and blue are formed on the reflective liquid crystal panel (40), a microlens array is formed on an input/output side substrate (50), and on an opposite side substrate (60), a reflection layer is formed corresponding to each pixel. The laser beam of each color is distributed and collected by a microlens and inputted to the corresponding pixel, and is reflected by the corresponding reflection layer. A refractive optical element can be used instead of the diffractive optical element. |
