Display device

A display device including a display area, which includes a thin-film transistor, and a pad area, which is disposed on a periphery of the display area, the display device comprising:

• a substrate;
• a first conductive layer disposed on the substrate, the first conductive layer including a gate electrode of the thin-film transistor, which is disposed in the display area, and a gate signal wire, which is disposed in the pad area;
• a first insulating layer disposed on the first conductive layer;
• a second conductive layer disposed on the first insulating layer, the second conductive layer including source and drain electrodes of the thin-film transistor and a plurality of wire pads which are disposed in the pad area;
• a second insulating layer disposed on the second conductive layer;
• and
• a third conductive layer disposed on the second insulating layer, wherein
• the plurality of wire pads overlaps, in a thickness direction, with, and is electrically connected to, the gate signal wire, each of the plurality of wire pads including:
• a main pad portion, which extends in a first direction;
• a first protruding pad portion, which protrudes from a first side, in a second direction which intersects the first direction, of the main pad portion;
• and
• a second protruding pad portion, which protrudes from a second side, in the second direction, of the main pad portion, and
• the first protruding pad portion is disposed closer than the second protruding pad portion to the display area.
