Patent ID: 8294652

Claim:
A driving method of a liquid crystal display panel having a source line and a counter electrode, said driving method comprising: driving the counter electrode to a first potential being a high level of an amplitude of a potential of the counter electrode; setting the counter electrode and the source line to a second potential by short-circuiting the counter electrode and the source line to a power supply interconnection having the second potential lower than the first potential, after the driving; connecting the counter electrode to a ground interconnection having a ground potential while the source line is kept to be short-circuited to the power supply interconnection, after the setting; driving the counter electrode to a third potential being a low level of an amplitude of a potential of the counter electrode, after the connecting; and driving the source line to a potential corresponding to an image data, after the connecting, wherein the setting of the counter electrode and the source line to the second potential occurs in a period of one frame.
