Patent ID: 7173598

Claim:
A driving method for an active-matrix liquid crystal display device, in which a pixel electrode is connected to a data signal line by a switching device based on a control signal supplied from a scan driver, and a data signal output from a data driver is supplied to the pixel electrode through the data signal line, so that a picture based on the data signal is displayed by a pixel matrix, wherein: in performing black display in an upper black display area provided in an upper position of a screen and in a lower black display area provided in a lower position of the screen, a stabilization period is provided, in one vertical scan period, between a first black display period in which black display is performed in the upper black display area and a video display period in which video display is performed in a video display area below the upper black display area and between the video display period and a second black display period in which black display is performed in the lower black display area below the video display area, said stabilization period being a period in which a frequency of a clock signal for operating a shift register included in the data driver is made lower than a frequency of the clock signal in the video display period such that a potential level at an internal node of the shift register is stabilized.
