Abstract

See full text

A pressure sensitive touch panel in which the position of an inner periphery of a window frame is disposed opposite to spacers, whereby a conductive film, which bends together with a flexible insulating plate when an operator presses the window frame, is caught by the spacers. In addition, protrusions are provided above the surface of an insulating layer, and inserted between the window frame and the flexible insulating plate or between the insulating layer and the conductive film, whereby the conductive film does not contact the upper edge of the end portion of the insulating layer. Thus, it is possible to avoid the damage to the conductive film due to the bending of the window frame and to avoid input of unintended and erroneous position data of input coordinates.
