Abstract: A display device includes a display panel including a display region and a non-display region, and an input sensing circuit disposed on the display panel. The input sensing circuit includes a plurality of sensors overlapping the display region and including a plurality of first sensors and a plurality of second sensors capacitive-coupled respectively to adjacent first sensors among the plurality of first sensors, a dummy line disposed on a periphery of the plurality of sensors, extending along a part of a boundary between the display region and the non-display region, and insulated from the plurality of sensors, and a plurality of dummy patterns insulated from the plurality of sensors. Each of the plurality of dummy patterns is disposed between two adjacent sensors among the plurality of sensors, and at least a portion of the plurality of dummy patterns is electrically connected to the dummy line.
