Abstract:
The purpose of the present invention is to achieve further miniaturization and performance improvement in a pressure detection-type touch panel. The touch panel (1) includes a TP upper side electrode layer (19) located above a CF substrate (18); and a TP lower side electrode layer (16) located below the CF substrate (18) and above a liquid crystal layer (14); an ITO layer (13) located above the TFT substrate (11) and below the liquid crystal layer (14); and a piezoelectric element layer (15) located between the TP lower side electrode layer (16) and the ITO layer (13).
