Abstract: A display device that includes a light emitting element disposed on a display area, a first signal pad electrically connected to the light emitting element and disposed in a non-display area adjacent to the display area, and a second signal pad spaced apart disposed in the non-display area. The display device may include an insulating layer overlapping an edge of the first signal pad and an edge of the second signal pad and disposed in the non-display area; a lighting circuit part disposed between the first signal pad and the second signal pad on the non-display area, and an organic protection layer overlapping the lighting circuit part and disposed in the non-display area, The insulating layer may be disposed between the lighting circuit part and the organic protection layer. Therefore, the display device may exhibit excellent reliability.
