Abstract

A display device includes a substrate including a display area and a peripheral area disposed around the display area, a pad area disposed near an edge of the substrate, and a plurality of pads disposed in the pad area and arranged along the edge of the substrate. An end of a first pad, which is an outermost pad among the plurality of pads, is connected to a first end of a resistor. The first pad is disposed between the resistor and the edge of the substrate, and a second end of the resistor is connected to a wire.
