Display device and method of driving the same

A display device includes a driving circuit that drives a pixel, and a display region including the pixel. The pixel includes a light emitting element electrically connected between a first power source and a second power source, a first transistor electrically connected between the first power source and the light emitting element to control a driving current, the first transistor including a first gate electrode electrically connected to a first node, and a second gate electrode electrically connected to a bias control line, and a switching transistor electrically connected between a data line and the first node, the switching transistor including a gate electrode electrically connected to a scan line. The driving circuit varies a control signal provided to the bias control line in a second period based on a first data signal provided to the data line during a first period.
