Abstract
A method of manufacturing a translucent screen and a rear projection display apparatus, onto which an image light emitted from an image source is projected, that includes first and second screen members that expand and contract with variations in ambient temperature and humidity. The second screen member has a relatively lower rigidity than the first screen member. The second screen member is secured on the first screen member so that the second screen member is held under tension by the first screen member at normal ambient temperature and humidity.
