Abstract: An organic light-emitting diode display is disclosed. The display includes a semiconductor layer formed over a substrate, a scan line formed over the semiconductor layer and configured to provide a scan signal, and a light emission control line formed over the semiconductor layer and configured to provide a light emission control signal. The display includes a data line configured to provide a data voltage and a driving voltage line configured to provide a driving voltage, wherein the driving voltage line crosses the scan line and is electrically insulated from the scan line. A switching transistor is electrically connected to the scan line and the data line and includes a switching drain electrode. A driving transistor includes a driving source electrode electrically connected to the switching drain electrode. Any one of the semiconductor layer and the light emission control line includes an extension at least partially overlapping the data line.

Abstract: An organic light emitting diode display includes a plurality of pixels. At least one pixel is connected to a scan line receive a scan signal, a data line to receive a data signal, and voltage line to receive a driving voltage. The at least one pixel includes a switching transistor including a switching drain electrode to output the data voltage, a driving transistor including a driving source electrode connected to the switching drain electrode, and an organic light emitting diode connected to a driving drain electrode of the driving transistor. The driving source electrode is separated from the data line.
