Patent ID: 7986376

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate; liquid crystal composition which is sandwiched between the first substrate and the second substrate; a plurality of pixel electrodes which are formed on the first substrate; counter electrodes which are arranged to face the pixel electrodes in an opposed manner; switching elements which are configured to supply video signals to the pixel electrodes; video signal lines which are configured to supply video signals to the switching elements; scanning signal lines which are configured to supply scanning signals for controlling the switching elements; first counter electrode signal lines which are configured to supply a first voltage to the counter electrodes; second counter electrode signal lines which are configured to supply a second voltage to the counter electrodes; and a driver circuit which is configured to output the video signals and the scanning signals, wherein a first scanning signal line and a second scanning signal line which constitute two neighboring scanning signal lines are provided with first pixel electrodes to which the video signals are supplied from the switching elements which are controlled in response to the scanning signals supplied through the first scanning signal line, and second pixel electrodes to which the video signals are supplied from the switching elements which are controlled in response to the scanning signals supplied through the second scanning signal line, a first counter electrode signal line is connected to the counter electrodes which face the first pixel electrodes in an opposed manner, a second counter electrode signal line is connected to the counter electrodes which face the second pixel electrodes in an opposed manner, the liquid crystal display device is driven in a first mode in which polarity of a voltage applied to the first counter electrode signal line and polarity of a voltage applied to the second counter electrode signal line are set opposite to each other during a first scanning period in which the scanning signals are outputted to the first scanning signal line, and the liquid crystal display device is configured to be capable of selecting a second mode in which the voltage applied to the first counter electrode signal line and the voltage applied to the second counter electrode signal line have the same polarity during a retracing period from a point of time that outputting of the scanning signal to the scanning signal line on the last row is finished to a point of time that outputting of the scanning signal to the scanning signal line on a start row is started.
