A plurality of liquid crystal modules is vertically and horizontally arranged, each of which is supplied light by a light source via optical fibers. A screen can be wound up at a cabinet. An image from each of the plurality of liquid crystal modules does not interfere one another because a light shielding board is installed.

A semiconductor laser excited solid laser device of side light excited type in which the excitation region is well matched with the mode volume of the laser oscillation mode, for providing high output and high efficiency. The semiconductor laser excited solid laser device comprises a diffraction grating for diffracting the output light beams of the semiconductor lasers in a direction of formation of the laser resonator mode in application of the output light beams to the solid laser medium.
