ABSTRACT:
A liquid crystal display device includes a video signal line drive circuit which includes (1) a first drive voltage circuit including at least one first output circuit which outputs an LC driving voltage of positive polarity corresponding to display data, and at least one second output circuit which outputs an LC driving voltage of negative polarity corresponding to display data, the at least one first output circuit and the at least one second output circuit being arranged alternately in a first polarity order, (2) a second drive voltage circuit including at least one third output circuit which outputs an LC driving voltage of positive polarity corresponding to display data, and at least one fourth output circuit which outputs an LC driving voltage of negative polarity corresponding to the display data, the at least one third output circuit and the at least one fourth output circuit being arranged alternately in a second polarity order opposite to the first polarity order, (3) a first switching circuit which inputs display data to the first voltage drive circuit and the second voltage drive circuit in two different input orders which are alternated, and (4) a second switching circuit which supplies outputs from the first drive voltage circuit and the second drive voltage circuit to video signal lines of a liquid crystal display panel in two different output arrangements which are alternated in synchronism with the alternation of the two different input orders.
