Patent ID: 7692728

Claim:
A touch panel comprising: a light-transmissive upper substrate; an upper conductive layer disposed on a bottom surface of the light-transmissive upper substrate; a light-transmissive lower substrate; a lower conductive layer disposed on a top surface of the light-transmissive lower substrate so as to face the upper conductive layer at predetermined spaced intervals; and a polarizing plate attached on a top surface of the upper substrate, the polarizing plate being a laminated structure including (i) a polarizing layer, (ii) an upper protective layer, and (iii) a lower protective layer, wherein the polarizing layer is sandwiched between the upper protective layer and the lower protective layer, wherein the lower protective layer directly contacts a lower surface of the polarizing layer, and wherein the lower protective layer is a phase-difference layer with ¼ wavelength made of a cycloolefin-based polymer.
