Patent ID: 8675147

Claim:
A protection panel provided with a touch input function for a display window of an electronic device, the protection panel being fitted and retained with no gap in a panel fitting portion of a casing provided with an opening such that an outer surface of the protection panel forms one plane together with a periphery of the casing, and protecting a display device disposed therebelow so as to be externally visible through a transparent window portion, the protection panel comprising: a protection panel main body including a plastic plate having a glass plate fitting opening punched out so as to be larger than the transparent window portion, and a glass plate fitted in the glass plate fitting opening; a lower electrode sheet including a transparent resin film for the lower electrode sheet, a lower transparent electrode in a quadrilateral shape, and a lower circuit surrounding the lower transparent electrode, the lower transparent electrode and the lower circuit being provided on an upper surface of the transparent resin film for the lower electrode sheet, the lower electrode sheet being attached to an upper surface of the plastic plate and an upper surface of the glass plate of the protection panel main body; an upper electrode sheet including a transparent resin film for the upper electrode sheet, an upper transparent electrode in a quadrilateral shape, and an upper circuit surrounding the upper transparent electrode, the upper transparent electrode and the upper circuit being provided on a lower surface of the transparent resin film for the upper electrode sheet, the upper electrode sheet being bonded to the lower electrode sheet at peripheral edges thereof so as to form a gap between the lower transparent electrode and the upper transparent electrode; and a decorative sheet including a transparent resin film for the decorative sheet, and a decorative layer that is provided on at least one surface of the transparent resin film for the decorative sheet so as to hide the lower circuit and the upper circuit and form the transparent window portion, the decorative sheet being attached to an upper surface of the upper electrode sheet.
