Claim Text:
1. A liquid crystal display device, comprising: image signal lines; a plurality of pixel circuits that is connected to the image signal lines; an image signal line driving circuit that is connected to the image signal lines, and sequentially outputs an image signal indicative of a display gray level of the plurality of pixel circuits; a plurality of gate lines that is connected to the respective pixel circuits; and a gate line driving circuit that supplies a scanning signal for storing the image signal in the pixel circuits connected to the gate lines, to the respective gate lines, wherein a frame inversion signal indicating a polarity of the image signal of each frame is input to the image signal line driving circuit, wherein a long cycle inversion signal indicating a polarity of the image signal of several sequential frames is input to the image signal line driving circuit, wherein the image signal line driving circuit outputs a first polarity pattern to the plurality of pixel circuits when both of a voltage of the frame inversion signal and a voltage of the long cycle inversion signal are one of high-level and low-level, wherein the image signal line driving circuit outputs a second polarity pattern to the plurality of pixel circuits when one of a voltage of the frame inversion signal and a voltage of the long cycle inversion signal is high-level and other thereof is low-level, wherein the second polarity pattern is different from the first polarity pattern.
