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 the CF substrate (18), a TP lower side electrode layer (15) located below the CF substrate (18) and above the liquid crystal layer (14), and a piezoelectric element layer (16) located between the TP upper side electrode layer (19) and the TP lower side electrode layer (15).
