Abstract (en)
In driving the liquid crystal panel, the frequency of the base voltage applied to common electrodes is reduced without increasing flickering. Also, the deterioration of picture quality caused by concentration of current to the common electrodes is reduced. In a liquid crystal panel 101 having pixel portions 104, each including a thin film transistor, mounted thereon, a liquid crystal 107 and additional capacitors 108 as components of each pixel portion, have a common opposite electrode 112 on one side thereof opposite to the side where there is a pixel electrode 106. The opposite electrodes 112 of the pixel portions 104 connected to the same gate line 102 are divided in half and are respectively connected to two separate and opposite electrode lines 109, 110. <IMAGE>
