PROBLEM TO BE SOLVED: To provide an assembly structure effective to maintain a suitable initial state when attaching a transmission type screen constituted by combining a flexible lens sheet (having no freestanding property) with a rigid lens sheet (having freestanding property) to a TV main body. SOLUTION: In such a state that the surfaces on the lens part sides of a lenticular sheet and a Fresnel lens sheet having nearly equal size are opposed, and the peripheries of these sheets are sealed with an adhesive tape so that the resultant cross section is U-shaped; the void between both sheets is sucked by a vacuum pump so as to be set in a decompressed state, and both the sheets are brought into tight-contact with each other. Thereafter, they are supported and fixed in a frame. COPYRIGHT: (C)2007,JPO&INPIT
