An input sensing unit including a plurality of first electrodes, each of which including a plurality of first main patterns and a plurality of connection patterns disposed between the first main patterns to connect two first main patterns adjacent to each other, a plurality of second electrodes each of which including a plurality of second main patterns and a plurality of connection patterns disposed between the second main patterns to connect two second main patterns adjacent to each other, and a plurality of third electrodes receiving an electrical signal that is different from that received by the second electrode. Each of the third electrodes includes a plurality of third main patterns spaced apart from the second sensing patterns in a plan view and a plurality of third connection patterns disposed between the third main patterns to connect two third main patterns adjacent to each other and spaced apart from the first connection patterns in a plan view.
