Touch panel

Abstract

The touch panel of the invention includes an optically transparent upper substrate having an upper conductive layer formed on an undersurface thereof, an optically transparent lower substrate having a lower conductive layer formed on an upper surface thereof and facing the upper conductive layer with a predetermined space, a spacer in a frame shape disposed between the upper substrate and the lower substrate, and a polarizing plate adhered to an upper surface of the upper substrate, in which the polarizing plate is adhered to the upper surface of the upper substrate within the outer periphery of the spacer. Because the polarizing plate is attached to the upper surface of the upper substrate but within an outer periphery of the spacer, even when the panel is exposed to a high temperature and high humidity environment, the substrate is prevented from being peeled off the spacer and a loose fitness of wiring substrate is avoided, thus a touch panel of an easy operation and a secure electrical connection is obtained.
