Abstract
A Liquid Crystal Display (LCD) device includes a liquid crystal panel in which a plurality of common electrodes are formed; an interred touch sensor for applying a common voltage to the common electrodes, and detecting a touch point of the liquid crystal panel with a capacitance that is induced in the common electrodes; a plurality of common electrode lines for connecting the common electrodes to the touch sensor; and an equivalent potential unit formed in the common electrode lines, and discharging residual electric charges of the common electrodes.
