Patent ID: 8390750

Claim:
A liquid crystal display device comprising: a liquid crystal display panel which includes a first substrate, a second substrate, and liquid crystal material which is sealed between the first substrate and the second substrate; and a plurality of scanning signal lines and a plurality of video signal lines which are arranged on the first substrate, wherein pixels, each of which includes a first TFT element, a first pixel electrode which is connected to a source of the first TFT element, a second TFT element, a second pixel electrode which is connected to a source of the second TFT element, and a counter electrode are arranged on the first substrate in a matrix array, a drain of the first TFT element and a drain of the second TFT element within the pixel are connected to different ones of the -video signal lines, respectively, the first pixel electrode and the second pixel electrode have a planar shape and include a plurality of comb-teeth portions, respectively, and the first pixel electrodes and the second pixel electrodes are arranged alternately on a same layer in an opposed manner with a gap defined between the comb-teeth portion of the first pixel electrode and the comb-teeth portion of the second pixel electrode, the first and second pixel electrodes and the counter electrode are arranged in a stacked manner with an insulation layer sandwiched therebetween, and the first pixel electrode and the second pixel electrode are arranged between the counter electrode and the liquid crystal material, and wherein a first level relationship between a potential of a grayscale voltage applied to the first pixel electrode and a potential of a voltage applied to the counter electrode during 1 frame period, and a second level relationship between a potential of a grayscale voltage applied to the second pixel electrode and the potential of the voltage applied to the counter electrode during the 1 frame period are reversed relative to one another.
