ABSTRACT:
A method for driving a liquid crystal of a thin film transistor liquid crystal display, the method comprising the steps of applying a first voltage corresponding to a real data during a data voltage applying frame and applying a second voltage for maintaining a bend state and preventing the liquid crystal from restoring to a splay state during a maintenance voltage applying frame, wherein the real one frame for driving the liquid crystal includes the data voltage applying frame and the maintenance voltage applying frame subsequent to the data voltage applying frame, and the data voltage applying frame is a data applying time and the maintenance voltage applying frame is a maintenance time, and the data voltage applying frame and the maintenance voltage applying frame are determined by a period of a signal applying to a gate of the liquid crystal display.
