Abstract
A liquid crystal display device includes: a liquid crystal panel having pixels with a first electrode and a second electrode; a control circuit; and a counter. The number and an arrangement of pixels where a potential of the second electrode is higher than that of the first electrode in a first mode equal the number and an arrangement of pixels where the potential of the first electrode is higher than that of the second electrode in a second mode. The counter increases a count while the panel operates in the first mode, and decreases the count while the panel operates in the second mode. The control circuit operates the panel in the first mode when the count at a determination timing is not greater than a first threshold, and operates the panel in the second mode when the count at the determination timing is not less than a second threshold.
