摘要:
The present invention provides a liquid crystal display device that appropriately compensates for a feed-through voltage. The liquid crystal display device is arranged such that when data of a certain gray level is to be displayed, the effective value of a pixel voltage changes in an N-frame cycle, a first pixel and a second pixel are provided that are different in the effective value during an i-th frame (1≦i≦N), the first pixel has a positive polarity during the i-th frame, whereas the second pixel has a negative polarity during an i{N/2 after}th frame, the first pixel has a polarity during a j-th frame (where 1≦j≦N and i≠j), the polarity being different from the polarity of the second pixel during a j{N/2 after}th frame, and when data of a first gray level is to be displayed, VB and VC are different from each other, where VA is a source voltage (VD) of the first pixel during the i-th frame, VB is a source voltage (VD) of the second pixel during the i{N/2 after}th frame, and VC is, in a case where data of a second gray level is to be displayed when the first pixel has a positive polarity during the j-th frame, a source voltage (VD) of the second pixel during the j{N/2 after}th frame for the case in which the source voltage (VD) of the first pixel during the first pixel is VA.
