<p>PURPOSE:To realize an active matrix driving system liquid crystal display device whose power consumption is little. CONSTITUTION:A counter electrode 13 opposed to a transparence electrode 12 on which a signal potential is given is independently and separately provided on each gate line, and the potential impressed on the counter electrode 13 can be independently controlled by each gate line. Thus, the adequate potential can be always supplied between the transparence electrode 12 and the counter electrode 13 regardless of the position of a line on a screen and a time when the polarity of the signal potential is inverted. As a result, a system power source voltage which must be excessivly set by the amount of the fluctuation of the signal potential in the danger of being caused when the polarity of the signal potential is inverted, but now it can be lowered. Thus, the power consumption can be made less than conventional device.</p> |
