Abstract
A display device includes: pixels to emit light of various intensity in accordance with driving signals; data lines to communicate the driving signals to the pixels; scan lines to communicate scan signals to select at least one of the pixels to receive the driving signal; and a power supply to supply at least one driving voltage to the pixels. The at least one pixel includes: a switching transistor including an oxide transistor, the switching transistor having a first electrode connected to the data line, a second electrode connected to a first node, and first and second gate electrodes, each of which is connected to one of the scan lines, and a driving transistor including a poly-silicon transistor, and the driving transistor being connected between the power supply and an organic light emitting diode.
