Abstract:
Disclosed is a touch panel device equipped with multiple touch position detection electrodes provided in a touch region, and a detection circuit that detects a touch position based on the electrostatic capacitance formed between the touch position detection electrodes and a contact body. The multiple touch position detection electrodes are equipped with first electrodes and second electrodes formed along a curved substrate surface. The first electrodes have a central part disposed in the center of the touch region and multiple tip parts that radiate toward the marginal edge of the touch region from the central part.
