Abstract: A touch sensor includes a substrate layer, sensing electrodes on the substrate layer, and at least one device hole penetrating through one or more of the sensing electrodes. The device hole is superimposed over a functional device of an image display device such that the functional device is not positioned in the device hole. The sensing electrodes include first sensing electrodes arranged along a first direction to form a first sensing electrode row and second sensing electrodes arranged along a second direction to form a second sensing electrode column, the first and second directions being perpendicular to each other on the substrate layer. The device hole is defined by a space between a pair of the neighboring first sensing electrodes and a pair of the neighboring second sensing electrodes.
