Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel with pixels in which a plurality of signal lines for transmitting display data and a plurality of scanning lines for transmitting control signals are laid out vertically and horizontally, said pixels are all driven with a same frame rate and pixel electrodes are arranged at intersections of said signal lines and said scanning lines via switching elements; and a control circuit for controlling said liquid crystal panel via said signal lines and said scanning lines, and for performing impulse driving to activate said control signals, which are to be transmitted to each of said scanning lines, during one frame period for displaying one image, wherein: said one image is divided into a first partial image and a second partial image, said one frame period is divided into a first partial frame period during which said first partial image is displayed and a second partial frame period during which said second partial image is displayed, said control circuit activates said control signals one time per one scanning line and per one partial frame period, said liquid crystal panel is divided into first pixel regions for displaying said first partial image and second pixel regions adjacent to said first pixel regions for displaying the second partial image; said display data are written in said first pixel regions and reset data are written in said second pixel regions, when said control signals are activated during the first partial frame period, and said reset data are written in said first pixel regions and said display data are written in said second pixel regions, when said control signals are activated during the second partial frame period.
