Patent ID: 8360582

Claim:
A rear projection type image display apparatus comprising: a projector configured to project an image having a relatively high luminance; a transmission type screen including a first screen having a fibrous texture configured to diffract light incident from the projector, and a second screen attached to the first screen on a side of the first screen opposite the projector and including diffusing particles to diffuse light incident from the first screen and output the diffused light; a first polarizing plate having a first polarization direction, the first polarizing plate disposed in front of an exit pupil of the projector and at a first distance from the transmission type screen; and a second polarizing plate having a second polarizing direction that is substantially orthogonal to the first polarizing direction, the second polarizing plate being disposed near a rear surface side opposite to an irradiation surface of the transmission type screen and at a second distance from the transmission type screen, which is smaller than the first distance, wherein only the first polarizing plate and the second polarizing plate are configured to polarize the image projected from the projector.
