摘要： A projection display apparatus having a light source for generating a white light, a liquid crystal panel for modulating an incident light from the light source, a polarizing plate which is located at a light exiting side of the liquid crystal panel for polarizing a light from the liquid crystal panel passed therethrough and a cooling liquid for cooling at least the liquid crystal panel and the polarizing plate. A projection lens device having plural lens elements which is located at a light exiting side of the polarizing plate is provided for projecting the light passed through the polarizing plate. One of the plural lens elements located nearest the polarizing plate has a negative refractive power in a center region containing an optical axis thereof and has a positive refractive power in a peripheral portion of the center region.

摘要： In order to prevent dust from sticking to the LCD panel, to prevent the LCD panel from being heated and to suitably adjust the position of the LCD panel, a duct is provided between cooling means for a light source and cooling means for a LCD panel to send cooling air from the LCD panel side to the light source side. Therefore, a light incidence/reflection plane of the LCD panel is disposed in an almost hermetically closed space and an optical path from an integrator lens to the LCD panel is formed in the almost hermetically closed space.
