Patent ID: 7561150

Claim:
A liquid crystal driving circuit for a liquid crystal display device, the liquid crystal display device including: an active matrix-type liquid crystal display region; display elements formed in the liquid crystal display region; switching elements to perform switching to cause the display elements to hold an image signal, each of the switching elements including an amorphous silicon thin film transistor, said driving circuit comprising: a first gate driver that drives the switching element on odd-numbered scanning lines in the liquid crystal display region; a second gate driver that drives the switching elements on even-numbered scanning lines in the liquid crystal display region; a source driver that supplies source pulses as the image signal to the display elements via the corresponding switching elements, the source pulses having a first pulse width during which the image signal is active high; and a clock generation circuit that generates multiphase clock signals in a form of clock pulses having a second pulse width, the clock signals being active high during the second pulse width, the clock signals being supplied to the first and second gate drivers, wherein the multiphase clock signals become active high one first pulse width before the image signal to be supplied to the display elements becomes active high, a falling of the clock pulse being set within an active high period of the corresponding source pulse, and the first and second gate drivers drive the switching elements in the active high period of the clock signals.
