Abstract:
A display device includes: a pixel including: a light emitting element connected between a first power source and a second power source; a first transistor connected between the first power source and the light emitting element to control a driving current, and including a first gate electrode connected to a first node and a second gate electrode connected to a bias control line; and a switching transistor connected between a data line and the first node, and including a gate electrode connected to a scan line; and a driving circuit to drive the pixel according to a driving frequency. The driving circuit drives the pixel in a first mode when the driving frequency is in a first range, and sequentially supplies a control signal having a first voltage and a second voltage to the bias control line during a light emission period of the pixel in the first mode.
