发明名称 LIQUID CRYSTAL PROJECTOR
摘要 <P>PROBLEM TO BE SOLVED: To suppress increase in the temperature of a liquid crystal panel, a polarizing plate or a display device. <P>SOLUTION: The shape of dust-resistant glass 41a and 41b of the liquid crystal panel is made into a rectangular shape, in which the long side is set as the short side of the effective pixel region of the TFT substrate 23, to make the surface area increase. The polarizing plate is also made into a rectangular shape, in which the long side is set as the short side of the polarization light transmitting region matched with the effective pixel region of the liquid crystal panel and to make the surface area increase. <P>COPYRIGHT: (C)2008,JPO&INPIT
