Display device including a common power supply line disposed in a peripheral area and overlapping a fan-out part

A display device, comprising:

• a substrate including a display area and a peripheral area outside the display area, wherein the display area has a non-quadrangular shape;
• a plurality of light-emitting diodes disposed in the display area, the plurality of light-emitting diodes including a first light-emitting diode that comprises a pixel electrode, an opposite electrode, and an intermediate layer between the pixel electrode and the opposite electrode;
• a plurality of data lines extending in a first direction in the display area;
• a fan-out part including a plurality of wirings, the plurality of wirings arranged in the peripheral area and electrically connected to the plurality of data lines;
• a driving circuit disposed in the peripheral area and comprising a plurality of circuit portions that are arranged along an outline of the display area;
• a line disposed in the peripheral area and electrically connected to the plurality of circuit portions of the driving circuit, wherein the line comprises at least one of a voltage line or a clock line;
• and
• a common power supply line disposed in the peripheral area and electrically connected to the opposite electrode of the light-emitting diode,
• wherein:
• the peripheral area comprises a first peripheral area and a second peripheral area that are opposite to each other with respect to a first virtual line that passes a center of the display area in a second direction crossing the first direction, and
• the fan-out part is disposed in the first peripheral area, and a common power supply line overlaps the fan-out part in the first peripheral area.
