Disclosed here is a touch panel with improved visibility. Polarizing plate ( 15 ) of the touch panel has a laminated structure in which polarizing layer ( 15 a) is sandwiched between upper protective layer ( 15 b) and lower protective layer ( 15 c). Of the three layers, lower protective layer ( 15 c) is formed as a phase-difference layer with ¼ wavelength made of a cycloolefin-based polymer. The structure protects polarizing plate ( 15 ) from distortion and deterioration, offering good visibility. At the same time, the structure above contributes to reduced parts count and accordingly cost-reduced touch panel.
