Display device compensating for deterioration of a pixel using an external compensation technology

A display device, comprising:

• a substrate including a display area and a non-display area located outside the display area;
• a driving circuit layer including a transistor disposed on the display area of the substrate;
• a first insulating layer disposed on the driving circuit layer;
• and
• a first conductive layer including first sensing wirings and auxiliary voltage wirings disposed on the first insulating layer,
• wherein the first sensing wirings and the auxiliary voltage wirings extend in a first direction and are arranged along a second direction perpendicular to the first direction to have a first distance,
• the first sensing wirings are spaced a second distance apart from each other in the second direction, the second distance being greater than the first distance, and are electrically connected to the transistor through a contact hole,
• the auxiliary voltage wirings are electrically connected to each other in the non-display area, and
• a DC auxiliary voltage is applied to the auxiliary voltage wirings.
