发明名称 Liquid crystal projector
摘要 <p>In a liquid crystal projector using a reflective and scattering or reflective type liquid crystal panel, a plurality of light sources are used, thereby securing sufficient brightness of an image, increasing the F-number of a projection lens, and miniaturizing and lightening the projector. A light source is arranged right next to the projection lens and an exhaust port is arranged on the front face of the projector, thereby preventing hot heat discharged from the exhaust port from being discharged toward peripheral equipment or the operator. <IMAGE></p>
