Abstract
PURPOSE: To form a bright image by enhancing the use efficiency of light by a polarizing plate by optically modulating two kinds of P and S polarized light obtained by separating white light by two light valves and synthesizing by a beam splitter and projecting an image. CONSTITUTION: The light of a xenon lamp 10 or the like separated as the two kinds of the S and P polarized light by the beam splitter 11 is guided by a mirror 12, and a picture signal is optically modulated by the light valve 13 transmitting the S polarized light and the light valve 14 transmitting the P polarized light, and the two kinds of polarized light are synthesized by the beam splitter 15 and the image is projected on a screen 17 by a projection lens 16. The light valve is formed of a transparent substrate where a thin film transistor 22 and a picture element electrode 23 are arrayed, a substrate 24 having the filter 27 of three primary colors and the polarizing plate 26 selecting either of the two kinds of the S and P polarized light. Thus, the use efficiency of the light is enhanced by the polarizing plate by separating the white light for the two kinds of the P and S polarized light, so that the bright image is formed.
