Abstract
A multi-display apparatus includes a plurality of rear projection-type display devices each in which projection light from image sources is projected through projection lenses onto a rear projection surface of a rear projection screen to form a picture image on a front viewing surface of the rear projection screen, the plurality of rear projection-type display devices being combined together in contiguous relation to one another to form a large screen. An overall front viewing surface of the large screen is formed into a concave surface curved both in a horizontal visibility angle direction and a vertical visibility angle direction. A light-absorbing portion is formed on the front viewing surface of the rear projection screen, and the light-absorbing portion absorbs projection light which passes through one rear projection screen, and is incident as external light on another rear projection screen, thereby preventing a picture image from being degraded.
