Abstract
A liquid crystal display element is arranged so that a scanning line electrode group and a signal line electrode group, which are formed by arranging a plurality of electrodes parallel, are placed in a direction where they intersect each other, and liquid crystal intervenes between these electrode groups, and input directions of signal voltages to be applied to the signal line electrode group are opposite in some electrode. As a result, nonuniformity of temperature on a display screen, which is caused by heat generation according to driving of the liquid crystal and causes variations of a driving property of the liquid crystal, is suppressed, and thus a satisfactory display state is realized.
