Abstract
To provide a low reflectance protection panel with decoration for a display window of an electronic apparatus, superior in productivity. A decorating film is laminated on the surface of a transparent protective plate: the decorating film forms at least a window forming layer having a transparent window portion on the surface of a hard coating film at the transparent protective plate side and is formed with a low reflectance processed layer on the opposite surface thereof: and a low reflectance processed layer is formed on the rear surface of the transparent protective plate. Or, a decorating film is laminated on a surface of an optical isotropic transparent protective plate being interposed by a polarizing plate, the decorating film forms at least a window forming layer having a transparent window portion on the surface of the hard coating film at the transparent protective plate side.

10. A manufacturing method of display window protection panels for an electronic apparatus fitted into a display window opening for protecting a portion of a display device, which is located under the display window opening in a casing of the electronic apparatus and exposed from the display window opening, the method comprising:
-
forming a plurality of decorating areas each including a window forming layer having a decorating portion formed in a portion of one surface of said hard coating film in a thin film state, in which a part not provided with said decorating portion is formed as a transparent window portion which transmits a portion of said display device exposed from said display window opening so as to be viewed, thereby producing a large size decorating film sticking said large size decorating film to a large size transparent protective plate having an area larger than one of the decorating areas so that said decorating portion is located opposing to a surface of said large size transparent protective plate; and cutting said stuck large size decorating film and large size transparent protective plate at one time in a position outer than said transparent window portion as well as inner side of the decorating area, thereby obtaining protection panels.
