<P>PROBLEM TO BE SOLVED: To improve reliability, with respect to the fixing among a plurality of sheets in a screen of performing image display, composed of the plurality of sheets having a lens shape. <P>SOLUTION: The screen 10 of performing image display is provided with a lenticular lens sheet 1 and a Fresnel lens sheet 2, fixed to the lenticular lens sheet 1 through heat welding. Thus, since the lenticular lens sheet 1 and the Fresnel lens sheet 2 are fixed to each other through heat welding, the fixing strength between the lenticular lens sheet 1 and the Fresnel lens sheet 2 degrading due to repeated distortions of a welding part caused by temperature variations or else, for example, as in the case of fixing the both with a welding agent. As a result, reliability can be improved with respect to the fixing between the lens sheets. <P>COPYRIGHT: (C)2007,JPO&INPIT |
