Patent ID: 7855722

Claim:
A Liquid Crystal Display (LCD) device, comprising: a liquid crystal panel having liquid crystal cells divided by scan lines and data lines and arranged in a matrix shape; a data driving circuit to supply an image signal to the liquid crystal cells via the data lines; a scan driving circuit to sequentially select and scan the scan lines and to control an on/off state of switching elements arranged in each of the liquid crystal cells; a timing controller to drive both the data driving circuit and the scan driving circuit, based on an externally inputted signal; and a common electrode driving circuit to drive a common electrode of the liquid crystal panel and to supply a common voltage to the common electrode, the common voltage including a DC voltage maintained during a first period of a first horizontal period (1H) and another voltage applied during a second remaining continuous period of the first horizontal period (1H), with the another voltage continuously having an opposite polarity compared to the image signal which is simultaneously supplied by the data driving circuit.
