Abstract
A liquid crystal display (LCD) device includes a data drive circuit that inverts polarities of data every 2k horizontal periods (k is an integer not less than 2); and an LCD panel including a plurality of data lines and a plurality of gate lines crossing each other to define a plurality of pixels, each pixel including a switching device, wherein source electrodes of the switching devices in the pixels arranged in a vertical direction are connected to two different data lines.
