Projector device

Abstract

In a projector device, a plurality of light source each including a lamp and a reflection mirror are arranged in parallel in an opposing relation to each other with optical axes thereof being offset such that light fluxes from the light sources are compressed in the offset direction, respectively. The compressed light fluxes are reflected at right angles by orthogonal reflecting surfaces of a reflection member including reflection mirrors or reflection prisms to form a plurality of parallel emitting lights in one direction. The projector device includes a condenser portion for condensing the parallel emitting lights to a single emitting light flux. The light fluxes from the light sources are passed through a polarizer portion before the incidence on the reflection member or after the emission from the reflection member such that the light fluxes become linear polarized lights having polarizing directions coincident with polarizing directions of liquid crystal panels. The single emitting light flux is decomposed to a red, green and blue color lights by an image forming portion and the red, green and blue color lights pass through the liquid crystal panels to spatially modulate the red, green and blue color lights to thereby form red, green and blue image lights. The red, green and blue image lights are synthesized to form a color image light, which is projected onto a screen by a projection lens.
