ABSTRACT:
A touch panel which is constituted by using an adhesive layer having a thickness which is 70% or more of a thickness of an approximately picture-frame-like spacer which allows respective outer peripheries of an upper substrate and a lower substrate to adhere to each other is provided. Due to such a constitution, when the touch panel is used under high temperature or in an environment where the temperature difference is severely large so that the thermal expansion or shrinkage is generated on upper substrate or lower substrate, these thermal expansion and shrinkage can be absorbed by the thick and soft adhesive layer. As a result, it is possible to suppress the peeling-off of upper and lower substrates thus realizing a surely manipulable touch panel.
