ABSTRACT:
A liquid crystal display device includes a liquid crystal display panel having a display section which is composed of a plurality of display pixels, a driving unit which drives the display pixels, and a control unit which controls the driving unit. A first substrate includes pixel electrodes which are disposed in association with the plurality of display pixels. A second substrate includes a counter-electrode which is opposed to the plurality of pixel electrodes. A pair of alignment films are disposed on the plurality of pixel electrodes and the counter-electrode, and control an alignment state of liquid crystal molecules, which are included in the liquid crystal layer, by rubbing treatment. Dummy display pixels are disposed on a terminal end side of the display section in a rubbing direction. A driving unit includes circuit for cyclically applying a reverse transition prevention signal to the dummy display pixels.
