Patent ID: 8212791

Claim:
A protection panel with a touch input function for a display window of an electronic device, which is configured to be fitted and retained with no gap in a panel fitting portion of a casing provided with an opening such that an outer surface thereof forms one plane together with a periphery, and which protects a display device disposed therebelow so as to be externally visible via a transparent window portion; the protection panel comprising: a protection panel main body configured by a transparent plate; a lower electrode sheet that has a rectangular lower transparent electrode on an upper surface of a transparent resin film and a lower circuit provided at a periphery of the lower transparent electrode, and that is laminated onto an upper surface of the protection panel main body; an upper electrode sheet that has a rectangular upper transparent electrode on a lower surface of a transparent resin film and an upper circuit provided at a periphery of the upper transparent electrode, and that is bonded to the lower electrode sheet at peripheral edges thereof with a gap being formed between the electrodes; a decorative sheet that has a decorative layer defining the transparent window portion at least on one surface of a transparent resin film so as to hide the lower circuit and the upper circuit, and that is laminated onto an upper surface of the upper electrode sheet; and an FPC (Flexible Printed Circuit) that has an end inserted between the lower electrode sheet and the upper electrode sheet, and that is connected by thermal compression bonding to output ends of the upper circuit and the lower circuit, wherein the protection panel main body has a thermal compression head inserting space at a portion corresponding to a portion bonded with the FPC by thermal compression, the thermal compression head inserting space reducing a distance between a surface of the protection panel main body and a surface of the lower electrode sheet at the portion corresponding to the portion bonded with the FPC by thermal compression, relative to a distance therebetween at a portion other than the portion corresponding to the portion bonded with the FPC by thermal compression, and the lower electrode sheet has an end surface recessed inwards to configure a turning FPC accommodating space that allows the FPC to turn to a rear side.
