Abstract: A driving circuit to drive a display apparatus includes first through third driving circuits to respectively receive first through third clock signals for respectively outputting a first gate signal with a gate-on voltage synchronized with rising edge timing of the corresponding clock signal in a first period in which data is supplied to the pixel in a frame period, a second gate signal with a gate-on voltage synchronized with rising edge timing of the corresponding clock signal in a second period for initializing a transistor of the pixel in the frame period, and a third gate signal with a gate-on voltage synchronized with rising edge timing of the corresponding clock signal in a third period for compensating for a threshold voltage of the transistor in the frame period. The rising edge timing of the second clock signal is different from the rising edge timing of the third clock signal.
