PURPOSE:To obtain a uniform image over the entire surface of the display part of a liquid crystal display device by making the application time of a scanning voltage applied to scanning electrodes shorter than the application time of a signal voltage applied to picture elements belonging to the scanning electrodes through the signal electrodes. CONSTITUTION:A pulse outputted from a controller 43 for liquid crystal driving, i.e. a start pulse S1 for the signal voltage and scanning voltage is inputted to a scanning electrode driver 45 and a signal electrode driver 47. At this time, the signal voltage and scanning voltage are applied to the signal electrodes and scanning electrodes respectively. The start pulse S1 is further inputted to a timer 61 as well, which outputs a signal S2 for turning off the scanning voltage to a scanning electrode driver 45 a time period equal to the scanning voltage application time tau after it is started with the start pulse S1. The time period wherein the scanning voltage is applied is controllable with the signal S2. This scanning is carried out for all the scanning electrodes (b1-bn) in order and a line sequential scan is made on condition that the scanning voltage application time is shorter than the signal voltage application time.
