Abstract: According to an aspect of the present disclosure, the display device includes: a substrate including a display area and a non-display area adjacent to the display area, a plurality of light emitting diodes disposed in the display area and each including a cathode, a contact electrode disposed in the non-display area, and a plurality of insulating layers disposed on the substrate. At least one of the plurality of insulating layers includes a plurality of protrusions disposed between the substrate and the contact electrode, and the contact electrode is composed of a convex portion overlapping with the plurality of protrusions and a concave portion between the plurality of protrusions. Therefore, according to the present disclosure, the surface area of the contact electrode is increased due to the plurality of protrusions so that a resistance between the contact electrode and the cathode can be reduced.
