Abstract
A touch sensor according to an embodiment of the present disclosure includes a substrate layer, sensing electrodes formed on the substrate layer, at least one device hole penetrating through at least one of the sensing electrodes, a barrier wall pattern formed along a periphery of the device hole, and an extension pattern disposed in the device hole to be connected to the barrier wall pattern. Defects caused by an external static electricity in the device hole can be prevented by the barrier wall pattern and the extension pattern.
