A touch panel used in a liquid crystal display device comprises a flexible electrode plate (21) made of a rigid transparent substrate (211) having a transparent conductive layer (212) on its upper surface and a flexible transparent substrate (222) having a transparent conductive layer (222) disposed on the lower side of the rigid electrode plate An electrode plate (22) is provided. A polarizing plate (24) is fixed to the upper surface of the flexible electrode plate. The flexible transparent substrate (221) includes a transparent film of amorphous plastic having a glass transition temperature of not less than 100.degree. C. the transparent film is expressed by: Cr = C / CPC The relative photoelastic coefficients CR values of 0.2 to 0.8 are defined by the photoelastic coefficients of polycarbonate films.
