Abstract:
Provided is a self-capacitance type touch sensor provided with a sensor electrode comprising a plurality of conductive wires. The sensor electrode has a first conductive portion and a second conductive portion connected to the first conductive portion. An occupancy that is the proportion of the area of the plurality of conductive wires in a predetermined unit area in the second conductive unit is lower than an occupancy that is the proportion of the area of the plurality of conductive wires in the predetermined unit area in the first conductive unit. The touch sensor makes it possible to increase sensing sensitivity while maintaining light transparency.
