Abstract
A liquid crystal display device in which each of the scanning electrodes has a center portion, an upper projection extending upwards from the center portion and a lower projection extending downwards from the center portion, and two picture elements are formed vertically each in an area comprising the upper projection and the center portion and an area comprising the lower projection and the center portion, and the phases in which the data to be given to the signal electrodes are sampled from even scanning picture signals are made different from the phases in which the data to be given to the signal electrodes are sampled from odd scanning picture signals, so that when the scanning electrodes are selected, the data for four scans of picture signals are given to the signal electrodes.
