1. A display device comprising:
a substrate comprising a display area displaying an image and a non-display area adjacent to the display area;
a plurality of pixels arranged in the display area, each of the plurality of pixels comprising:
a pixel circuit; and
a light-emitting diode including:
a pixel electrode electrically connected to the pixel circuit;
an emission layer; and
an opposite electrode;
a driving voltage supply line arranged in the non-display area, the driving voltage supply line supplying a driving voltage to the plurality of pixels;
a common voltage supply line arranged in the non-display area and electrically connected to the opposite electrode to supply a common voltage; and
a seal portion surrounding the display area,
wherein in a cross-sectional view of an area adjacent to a terminal portion, the common voltage supply line, the driving voltage supply line, and the seal portion are arranged in a direction away from the display area in an order of the common voltage supply line, the driving voltage supply line, and the seal portion such that a distance between a side of the display area facing the terminal portion and the common voltage supply line is less than a distance between the side of the display area and the driving voltage supply line in a direction perpendicular to the side of the display area.
