1. A rapidly driving liquid crystal display, comprising:

  • a liquid crystal panel having a plurality of pixels;

    a timing control circuit for issuing a gate clock signal and a plurality of control signals;

    a gray voltage generation circuit for generating a plurality of gray voltages corresponding to data to be displayed in the panel in response to the gate clock signal;

    a gate driving circuit for sequentially scanning the pixels of the panel row by row in response to the gate clock signal; and

    a source driving circuit for generating a liquid crystal driving voltage corresponding to data in response to the gray voltage and the control signals, and for applying the generated liquid crystal driving voltage to the panel each of scanning, wherein the source driving circuit generates a liquid crystal voltage having different values in high and low level intervals of the gate clock signal in response to the gray voltage.
