1. An organic light emitting diode display device comprising:
a substrate having a display region, a peripheral region at least partially surrounding the display region and including a first peripheral region, a second peripheral region, and a third peripheral region, and a pad region disposed on one side of the peripheral region, the second peripheral region between the first peripheral region and the third peripheral region in a plan view and the second peripheral region partially surrounding a first edge of the display region and a second edge of the display region, the second edge adjacent to the first edge;
a light emitting layer disposed on the substrate in the display region;
a first power supply disposed in the second and third peripheral regions and a part of the first peripheral region on the substrate;
a second power supply disposed in the display region, the first peripheral region, and the third peripheral region on the substrate without being disposed in the second peripheral region, and being at least partially surrounded by the first power supply;
a planarization layer disposed in the display region and a part of the peripheral region on the first power supply and the second power supply, and having an undulating shape in at least one of the first, second, or third peripheral regions;
a conductive pattern partially overlapped with the first power supply in the second and third peripheral regions and the part of the first peripheral region on the planarization layer, electrically connected to the first power supply, and having an undulating shape in at least one of the first, second, or third peripheral regions; and
an upper electrode disposed in the display region and the part of the peripheral region on the conductive pattern and the light emitting layer, partially overlapped with the first power supply and the conductive pattern, electrically connected to the conductive pattern, and having an undulating shape in at least one of the first, second, or third peripheral regions; and
wherein the first power supply has a first width in the second peripheral region and a second width in the third peripheral region, the second width less than the first width.
