1. A display device, comprising:
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 supplying a low-potential power voltage to the cathode; and
a plurality of insulating layers disposed on the substrate,
wherein at least one of the plurality of insulating layers includes a plurality of protrusions disposed to overlap with the contact electrode between the substrate and the contact electrode, and
wherein the contact electrode is composed of a convex portion overlapping with the plurality of protrusions and a concave portion between the plurality of protrusions, wherein the contact electrode includes:
a first conductive layer disposed on the substrate;
a second conductive layer disposed on the first conductive layer; and
a transparent conductive layer disposed on the second conductive layer and in contact with the cathode,
wherein the plurality of insulating layers includes:
a buffer layer disposed between the first conductive layer and the second conductive layer;
a gate insulating layer disposed between the buffer layer and the second conductive layer;
a passivation layer disposed between the second conductive layer and the transparent conductive layer; and
a planarization layer disposed between the passivation layer and the transparent conductive layer.
