Abstract: A display device including a substrate, a first upper power line, a conductive member, a protective insulating layer, an upper connection member, and a sub-pixel structure. The upper connection member is disposed in a first pad area and a first peripheral area on a planarization layer, and electrically connects the first upper power line and the conductive member through a first contact hole, which is formed in the protective insulating layer and the planarization layer located on the conductive member, and a second contact hole, which is formed in the protective insulating layer and the planarization layer located on the first upper power line.

Abstract: A pixel includes first to fourth transistors and a driving transistor. The first transistor is connected between a data line and a first node and has a gate electrode to receive a scan signal. The driving transistor is connected between the first node and a second node and has a gate electrode connected to a third node. The second transistor is connected between the second and third nodes and has a gate electrode to receive the scan signal. The third transistor is connected between first power and the first node and has a gate electrode to receive an emission signal. The fourth transistor is connected between the first and second nodes and has a gate electrode to receive an initialization signal. An organic light emitting diode is connected between the second node and second power. A storage capacitor is connected between the first power and third node.

Abstract: An organic light emitting diode display device includes a display panel and a power supply. The power supply applies a first power supply voltage and a second power supply voltage to a first power supply voltage line. The first power supply voltage line includes a first extension, a second extension, and third extension. The first extension is disposed along a first direction from the first side portion to the second side portion. The first extension has a width that gradually decreases along the first direction. The second extension is disposed along a second direction that is perpendicular to the first direction. The third extension is disposed along a third direction that is opposite to the first direction. The third extension has a width that gradually decreases along the third direction.
