Patent ID: 8384639

Claim:
A liquid crystal display device that performs line inversion drive, comprising: a pixel array including a plurality of pixels disposed in row and column directions, a plurality of scanning signal lines each commonly connected to the pixels disposed in the same row, and a plurality of data signal lines each commonly connected to the pixels disposed in the same column; a correcting circuit for obtaining a correction video signal by storing a video signal supplied from a signal source and performing correction for emphasizing temporal signal change between frames on the supplied video signal; a scanning signal line drive circuit for sequentially selecting and activating the scanning signal lines; and a data signal line drive circuit for applying a voltage corresponding to the correction video signal to the data signal lines, while changing its polarity every number of line periods, wherein the correcting circuit performs a first correction for emphasizing the temporal signal change when the polarity of the voltage applied to the data signal line is positive and performs a second correction for emphasizing the temporal signal change when the polarity of the voltage applied to the data signal line is negative, and the first and second correction includes modifying a value of a current frame of the supplied video signal such that the temporal signal change is emphasized, when the value of the current frame is greater than a value of a previous frame, then an amount that the value of the current frame is modified using the first correction is greater than to an amount that the value of the current frame is modified using the second correction, and when the value of the current frame is less than the value of the previous frame, then the amount that the value of the current frame is modified using the first correction is less than to an amount that the value of the current frame is modified using the second correction.
