Organic light emitting diode display

A display device, comprising:

• a substrate;
• a semiconductor layer on the substrate, the semiconductor layer including a plurality of channels and a plurality of electrodes;
• a scan line including a switching gate electrode overlapping a switching channel of the plurality of channels;
• a storage line including a storage electrode;
• a data line crossing the scan line and for transmitting a data voltage;
• a driving voltage line crossing the scan line and for transmitting a driving voltage;
• a switching transistor including the switching channel, the switching gate electrode, a switching electrode of the plurality of electrodes, and an electrode of the plurality of electrode, wherein the electrode includes a first end disposed at a side of the switching channel, and the switching electrode is electrically connected to the data lines;
• a driving transistor including a driving channel of the plurality of channels, a driving gate electrode overlapping the driving channel, the electrode, and a driving electrode, wherein the electrode includes a second end disposed at a side of the driving channel;
• and
• a storage capacitor including the driving gate electrode and the storage electrode overlapping each other, wherein
• the electrode comprises a first portion extending substantially parallel to the data line, an entirety of the first portion being separated from the data line in a plan view, and
• at least a portion of the first portion overlaps the storage electrode in the plan view.
