Abstract:
The purpose of the present invention is to provide a projection type image display apparatus which is simple in configuration, low in price, and improved in reliability and brightness of an illumination light source. The present invention is a projection type image display apparatus provided with: a lamp; a reflector that reflects a light flux emitted from the lamp; a collimating lens that collimates the light reflected by the reflector; a light modulation device that modulates the collimated light to output the modulated light; and a projection lens that projects the modulated light. The reflector is configured to prevent the lamp from being irradiated with the reflected light of the light flux emitted from the lamp, and the collimating lens is formed of one biconcave lens having concave surfaces on both the incident side and the exit side.

Claim (Index 6):
The projection type image display apparatus according to  claim 1 , further comprising:\n an illumination optical system that increases uniformity of illuminance of the collimated light and forming an illumination light; a color separation optical system that separates the illumination light formed by the illumination optical system into color lights of three colors of red (R), green (G), and blue (B); a light modulation device for each color, the light modulation device modulating each of color lights emitted from the color separation optical system and outputting a modulated light; a cross dichroic prism that combines the modulated light from the light modulation device; and a projection lens that projects an image light by the combined light formed via the cross dichroic prism.
