1. A display device, comprising:
a display panel including a plurality of pixels;
an input sensor including:
first detection electrodes arranged in a first direction and each extending in a second direction crossing the first direction;
second detection electrodes arranged in the second direction and each extending in the first direction;
first detection wires respectively electrically connected to the first detection electrodes;
second detection wires respectively electrically connected to the second detection electrodes, and disposed on the display panel; and
a circuit board disposed adjacent to an end of the display panel, the circuit board extending in the first direction and electrically connected to the first and second detection wires,
wherein resistance values of the first detection wires decrease as a corresponding first detection electrode, among the first detection electrodes, is disposed further towards a center of the display panel,
wherein resistance values of the second detection wires increase as a corresponding second detection electrode, among the second detection electrodes, moves away from the circuit board, and a difference between the resistance values of adjacent members of the second detection wires increases as the corresponding second detection electrode moves away from the circuit board,
wherein the display panel comprises an active area in which the pixels are disposed and a peripheral area proximate to the active area,
wherein the pixel comprises a driving circuit including at least one transistor, and a light emitting element including a first electrode electrically connected to the driving circuit, a second electrode, and a light emitting layer disposed between the first and second electrodes,
wherein noise generated from the second electrode increases towards a center of the active area in the first direction, and increases away from the circuit board in the second direction, and
wherein a rate of increase in the second direction of the noise generated from the second electrode decreases as a distance from the circuit board increases.
