Abstract:
A display device includes a first substrate, a wire pad in a pad area, first banks in a display area, electrodes on the first banks, a pad electrode base layer on the wire pad, having a greater width than the wire pad, and covering sides of the wire pad, a first insulating layer covering parts of the electrodes and part of the pad electrode base layer, light-emitting elements on the first insulating layer in the display area, respective ends of the light-emitting elements being on different electrodes, contact electrodes on the electrodes and contacting first ends of the light-emitting elements, and a pad electrode upper layer on the first insulating layer in the pad area and directly contacting the pad electrode base layer, wherein the pad electrode base layer includes the same material as the electrodes, and the pad electrode upper layer includes the same material as the contact electrodes.
