Abstract: A touch sensor includes a base layer, electrode units, and loop-shaped first lines. The electrode units are disposed on the base layer. The electrode units are arranged in a first direction and a second direction crossing the first direction. The loop-shaped first lines are in a same layer as the electrode units. The loop-shaped first lines are disposed between some of the electrode units, which are adjacent in the second direction. The loop-shaped first lines include resistance lines extending in the first direction and connection lines extending in the second direction. Some of the resistance lines, which are adjacent in the second direction, are connected by a connection line among the connection lines. The connection lines are spaced apart from each other in the first direction.
