    Abstract: Picture element electrodes (30) and common electrodes (36) are provided in one of two substrates facing each other. Each picture element (20) has a plurality of sub picture elements (22). In a range in which a signal voltage of an image signal is low, a display is carried out only in a first sub picture element (22a) having narrower electrode spacing, whereas in a range in which the signal voltage of the image signal is high, a display is carried out in both of the first sub picture element (22a) and a second sub picture element (22b) having wider electrode spacing.
