1. A gate driving circuit in a liquid crystal display having a liquid crystal panel with thin film transistors and pixel electrodes for displaying an image, a source driving circuit for applying video data to a source line in the liquid crystal panel, and a gate driving circuit for applying a driving signal to a gate line in the thin film transistors, the gate driving circuit comprising:

  • a plurality of gate line drivers connected in series for applying the driving signal to the gate line; and

    a plurality of clock generation controlling units corresponding to the plurality of gate line drivers each for controlling a timing of a clock signal to a respective gate line driver and each including a first flip flop connected as a toggle flip flop, thereby controlling a driving timing of the respective gate line driver.
