Projection type display apparatus |
摘要 |
This specification discloses a projection type display apparatus in which the lights of a plurality of display means forming images of different color component lights are reflected by or transmitted through a dichroic mirror to effect color synthesis and the synthesized lights are projected onto a screen by a projection lens. The astigmatism created by the lights being transmitted through the obliquely disposed dichroic mirror is suppressed to thereby obtain a good quality of image.
