Abstract
A touch panel includes a touch sensor panel including a touch sensor capable of detecting a change in electrostatic capacitance formed between the touch sensor panel and a pointer, a pressure sensor capable of detecting a pressure on a touch surface of the touch sensor panel as a change in electrostatic capacitance, and a shield layer. The shield layer is disposed between the touch surface and the pressure sensor so as to be overlapped with at least a part of the pressure sensor as viewed from the touch surface.
