1. A display device comprising:
a first substrate having a display area and a non-display area on one side of the display area;
a second substrate arranged opposite the first substrate;
a display element arranged on the display area, the display element including a pixel electrode, an intermediate layer arranged on the pixel electrode, and an opposite electrode arranged on the intermediate layer;
at least one power supply line arranged on the non-display area, the at least one power supply line comprising a first power supply line adjacent to the display area and supplying a first power supply voltage to a driving voltage line for the pixel electrode, and a second power supply line adjacent to the first power supply line and supplying a second power supply voltage to the opposite electrode;
a conductive layer directly arranged on at least a portion of the second power supply line between the first power supply line and the second power supply line and including the same material as the pixel electrode; and
a sealing portion disposed on the second power supply line adjacent to the conductive layer in the non-display area,
wherein the conductive layer clads at least a portion of an upper surface of the second power supply line,
wherein the conductive layer clads a first side surface of the second power supply line and wherein the first side surface of the second power supply line is adjacent to the first power supply line, and
wherein the conductive layer exposes a second side surface of the second power supply line and wherein the second side surface of the second power supply line is located opposite to the first side surface of the second power supply line.
