Patent ID: 7880716

Claim:
A liquid crystal display device comprising: a plurality of liquid crystal pixels which are arrayed substantially in a matrix; a plurality of signal line groups each including a predetermined number of signal lines which are arranged along the columns of liquid crystal pixels; and a drive circuit which selects the liquid crystal pixels on a row-by-row basis and drives the liquid crystal pixels of the selected row via the signal lines; wherein the drive circuit includes: a signal line driver which outputs a predetermined number of pixel voltages, which are assigned to the predetermined number of signal lines included in each of the signal line groups, in a parallel fashion for each group driving period while the liquid crystal pixels of each row are being selected; a multiplexer which distributes to each of the signal line groups the predetermined number of pixel voltages output from the signal line driver in the cycle of group driving period; and a controller which controls, in a case where output voltage polarities of the signal line driver are to be inverted in units of a predetermined number of pixel rows, the multiplexer to electrically connect all of the signal line groups to the signal line driver and electrically disconnect the signal line groups one by one from the signal line driver in a sequential fashion for each group driving period in a selection period of the liquid crystal pixels of an initial row that requires polarity inversion.
