Abstract:
An illumination optical system of a projector apparatus includes a rod lens which equalizes illuminance of illumination light incident on a micromirror device from lamps, and a plurality of light-shielding plates that shields unnecessary light not incident on the rod lens among the illumination light. The plurality of light-shielding plates is disposed on the incidence side of the rod lens such that each light-shielding plate is provided at a predetermined gap in an optical axis direction of the rod lens. Openings of each light-shielding plate are formed such that a light-shielding plate disposed on an emission side has a smaller passage area of illumination light than on an incidence side.

Claim (Index 3):
The projector apparatus according to  claim 1 , wherein a light-shielding plate disposed at least closest to the incidence side among the plurality of light-shielding plates has a low reflectance by processing the surface to a roughened surface state.
