A driving method is used for a liquid crystal device of the type comprising a pair of oppositely disposed electrode plates having thereon a group of scanning lines and a group of data lines, respectively, and a liquid crystal disposed between the pair of electrode plates so as to form a pixel at each intersection of the scanning lines and data lines. In the driving method, for displaying a halftone, a data line is supplied with a halftone signal selected from plural halftone signals determined according to a first relationship between applied voltage and transmittance of a pixel. On the other hand, for displaying a minimum or a maximum transmittance, a data line is supplied with an extreme signal determined according to a second relationship, different from the first one, between applied voltage and transmittance of a pixel. The extreme signal is applied for displaying a minimum or maximum transmittance state. As a result, a gradational display is performed at a high contrast ratio even when a temperature change occurs.
