Abstract

A touch sensor includes first electrodes which are driving electrodes of the touch sensor, second electrodes which are detecting electrodes of the touch sensor, third electrodes, and an insulating film which is stacked on the first electrodes. Each of the first electrodes extends in a first direction. Each of the second electrodes and each of the third electrodes are formed on the insulating film, and extend in a second direction. The second electrodes overlap with partial regions of the first electrodes, and the third electrodes overlap with other partial regions of the first electrodes and are formed in gaps between the second electrodes. A film thickness of the insulating film between the first electrodes and the third electrodes varies due to pressing force in a film thickness direction, and the insulating film constitutes the electrostatic capacitance-type pressure sensor with first electrodes and the third electrodes.
