1. A display device comprising:
a substrate including a display area and a non-display area surrounding the display area;
a gate driving circuit disposed on the substrate in the non-display area;
a light emitting element disposed on the substrate in the display area and including a cathode electrode;
a dam disposed on the substrate in the non-display area, the dam disposed further outside the substrate than the gate driving circuit;
a first dummy conductive layer covering the dam in the non-display area and made of a same material as the cathode electrode; and
a spacer disposed on the substrate between the gate driving circuit and the dam in the non-display area,
wherein the cathode electrode extends from the display area to the non-display area and overlapping with the gate driving circuit.
