    Abstract: A scan driver includes scan signal outputting circuits, at least one of the scan signal outputting circuits includes a driving circuit and a buffer circuit. The driving circuit includes driving transistors. The driving circuit provides first and second driving signals to first and second driving nodes, respectively by turning on or off the driving transistors in response to clock signals and a scan input signal. The buffer circuit includes buffer transistors. The buffer circuit outputs a scan signal at an output node by turning on or off the buffer transistors in response to the first and second driving signals. The at least one of the scan signal outputting circuits performs a back-biasing voltage applying operation on at least one of the driving transistors and the buffer transistors when the driving transistors and the buffer transistors are turned on or off.

    Abstract: An organic light-emitting diode display is disclosed. In one aspect, the display includes a display panel including pixels and having first and second end portions opposing each other, and a center portion therebetween. First and second power supply voltage lines extend from the first end portions to the second end portions. A third power supply voltage line having first and second ends are respectively formed in the first and center portions. A fourth power supply voltage line has first and second ends respectively formed in the first and second end portions. A power supply unit is formed adjacent to the first end portion and configured to apply a first power supply voltage to the first ends of the first and second power supply voltage lines and a second power supply voltage to the first end of the third power supply voltage line.
