摘要： 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.
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.

摘要： PROBLEM TO BE SOLVED: To prevent the deformation of a protective panel of a flat panel display device, more particularly an electromagnetic wave absorption filter of a PDP to a rugged shape by its thermal deformation, etc., and the generation of moires by the contact thereof with the image display surface of the PDP unit and further, to eliminate the need for separate conductive members exclusive of fixing members at the time of fixing the electromagnetic wave absorption filter and a front part casing. SOLUTION: The electromagnetic wave absorption filter 2 is fixed onto the outer flank 5S of a frame portion 5 forming an aperture 1a of the front surface of the front part casing 1 by a conductive double coated adhesive tape 8 having flexibility in a direction parallel with the adhesive surface. As a result, the deformation of the electromagnetic wave absorption filter 2 by its heat or moisture is absorbed by its own elastic deformation of the double coated adhesive tape 8. Even more, the double coated adhesive tape 8 itself has electrical conductivity and, therefore, there is separately no need for the conductive fixing members.
