Abstract: A touch sensor includes a base layer; a first electrode member that includes a plurality of first electrodes arranged on the base layer and electrically connected to each other along a first direction, each of the first electrodes including a first opening; a second electrode member that includes a plurality of second electrodes arranged on the base layer and electrically connected to each other along a second direction that intersects the first direction; a conductive member that includes a plurality of conductive patterns electrically connected to each other along the first direction; and a proximity detector that is electrically connected to the conductive member and configured to detect proximity of an object by receiving a proximity sensing signal from the conductive member. Each of the conductive patterns is located in the first opening of each of the first electrodes and spaced apart from each of the first electrodes, respectively.
