PROBLEM TO BE SOLVED: To control warp direction and amount appearing at the time of mounting and lighting by controlling the extension and contraction of a transparent high molecular molding and an optical film before sticking at the time of sticking the optical film and the transparent high molecular molding together. SOLUTION: The optical film 20 is stuck to the transparent high molecular molding 10 in an extended/contracted state. Also, an antidazzle film 30 is stuck on it and an antireflection film 40 is stuck on the opposite surface of the transparent high molecular molding 10. It is preferable that the transparent high molecular molding 10 is provided with excellent transparency and sufficient mechanical strength, is light in weight as much as possible and is hardly breakable. While acrylic resin and polycarbonate resin, etc., such as polymethylmethacrylate(PMMA) can be mentioned as the transparent high molecular molding 10, the PMMA among them can be suitably used from high transparency in the wide wavelength area and the height of the mechanical strength. The thickness of the high molecular molding 10 is not specially limited and is normally about 1-10 mm. Also, the optical film 20 is a transparent conductive thin film. |
