Abstract
A rear projection type image display apparatus. The apparatus includes a projector that projects an image having a relatively high luminance, and a transmission type screen installed at an image formation plane of a projection light from the projector. The apparatus also includes a first polarizing plate having a first polarization direction disposed in front of an exit pupil of the projector, and a second polarizing plate having a second polarizing direction that is substantially orthogonal to the first polarizing direction disposed near a rear surface side opposite to an irradiation surface of the transmission type screen.
