An enclosure has ducts formed therein and extending in a vertical direction along the left and right side surfaces as viewed from the rear side. The duct is formed in a region defined between a lefthand wall surface of the enclosure and a lefthand partition wall provided in the enclosure and in parallel to the lefthand wall surface. The screen side of the region defined between the lefthand wall surface and the lefthand partition wall is covered with a partition wall, and the opposite side of the region is covered with a cover not shown to serve as an air flow path. The duct is formed in a region defined between a righthand wall surface of the enclosure and a righthand partition wall provided in the enclosure and in parallel to the righthand wall surface. The screen side of the region defined between the righthand wall surface and the righthand partition wall is covered with a partition wall, and the opposite side of the region is covered with a cover not shown to serve as an air flow path.

Image display apparatus comprising an enclosure having first and second ducts and shut-off plates for ventilation

In an image-displaying screen that is formed of a plurality of plates having lens structure, the reliability of the fixing between the plurality of plates is enhanced. A screen that displays an image includes a lenticular lens plate and a Fresnel lens plate that is fixed to the lenticular lens plate by thermal welding. Because the lenticular lens plate and the Fresnel lens plate are thus fixed together by thermal welding, the fixing strength between the lenticular lens plate and the Fresnel lens plate is not deteriorated by repeated distortion of the welded portion, as would be caused by temperature variations etc. when a welding agent is used to fix them. This enhances the reliability of the fixing between the lens plates.
