1. A display device, comprising:
a substrate;
a plurality of organic light emitting elements provided on the substrate;
a plurality of pixel circuits, at least one of the pixel circuits including a first transistor including a first active pattern and a first gate electrode disposed on the first active pattern, a second transistor including a second active pattern connected to the first active pattern, wherein the second transistor includes a second gate electrode, and a third transistor including a third active pattern including a third channel connecting the first active pattern and the first gate electrode, wherein the third transistor includes a third gate electrode;
a first scan line, traversing the plurality of pixel circuits and connected to the second gate electrode and the third gate electrode;
a data line disposed on the first scan line, traversing the first scan line and connected to the second active pattern, and
a second scan line traversing the plurality of pixel circuits and connected to a bias electrode overlapping the first active pattern,
wherein the first transistor is reverse biased by a second scan signal applied to the second scan line connected to the bias electrode.
