| description | A rear projection display apparatus is provided which includes a transmission type screen installed on the front face of an apparatus main body, and a video projector disposed inside the apparatus main body and projecting video on the transmission type screen from the rear side thereof. The transmission type screen includes a lens sheet having respective ribs attached to upper and lower sides thereof, the ribs having increased thickness, and an upper bracket and a lower bracket attached to the lens sheet so as to retainably embrace the respective associated ribs. The upper bracket is fixed to a frame on an apparatus main body side, whereby the lens sheet is installed so as to be pulled downward by the weight of the lower bracket. The rib is formed by laminating the same materials as a substrate of the lens sheet. |
