Abstract
A liquid crystal display device includes a liquid crystal display panel; and a driver driving the liquid crystal display panel. The liquid crystal display panel includes: a first substrate on which subpixels each including a pixel electrode are integrated; and a second substrate opposed to the first substrate, a plurality of common electrodes being formed on the second substrate. The display region of the liquid crystal display panel is divided into a plurality of sections respectively corresponding to the common electrodes. When a partial display in which an image is selectively displayed in a selected section is performed, the liquid crystal driver drives the common electrode corresponding to the selected section to a predetermined common voltage level, sets the common electrodes corresponding to the non-selected sections to a predetermined reference level, and sets pixel electrodes of subpixels in the non-selected sections to the reference voltage level.
