Projection display

摘要

Disclosed is a projection display for projecting an image displayed on an image display element on a screen using light rays generated by a light source, wherein sheet-type polarized light separating mirrors each having a plane tilted at an angle of 10 to 30}K with respect to an optical axis of the light source are disposed between the image display element and the light source, whereby the projection display can be miniaturized with the reduced cost.
