A method for driving liquid crystal face plate includes dividing an image frame time to be the first and the second subimage frame times and setting the first and the second driving voltages, providing a back light source, exerting the first driving voltage on semipeneration pixel electrode and switching on back light source when it is on the first subimage frame time, exerting the second driving voltage on semipeneration pixel electrode and switching off back light source when it is on the second subimage frame time.
