1. A display device comprising:
gate lines and data lines disposed in a display area;
pixels disposed in the display area, the pixels being electrically connected to the gate lines, the data lines, a first power source line, and a second power source line such that current provided to the gate lines, the data lines, the first power source line, and the second power source line is supplied to the pixels;
a driving circuit supplying gate signals and data signals to the gate lines and the data lines, the driving circuit including a first circuit element disposed in the display area between pixel groups that are electrically connected to different ones of the gate lines and the data lines, each of the pixel groups include more than one of the pixels; and
a conductive pattern disposed in the display area and overlapping the first circuit element in a plan view, the conductive pattern electrically connected to the second power source line such that current provided to the second power source line is supplied to the conductive pattern, wherein
each of the pixels includes:
a pixel circuit including a driving transistor including an electrode electrically connected to the first power source line; and
an emission unit electrically connected to the pixel circuit, the emission unit including:
a first electrode electrically connected to another electrode of the driving transistor such that current provided to the first power source line is supplied to the first electrode through the driving transistor;
a second electrode electrically connected to the second power source line such that current provided to the second power source line is supplied to the second electrode; and
at least one light emitting element disposed and electrically connected between the first electrode and the second electrode,
the first electrode and the another electrode of the driving transistor are disposed on different layers, and
the conductive pattern, the first electrode, and the second electrode are disposed on a same layer.
