Abstract

A display device is disclosed. The display device comprises: a plurality of gate wires extending in a first direction; a plurality of data wires which intersect the gate wires, and which extend in a second direction; a plurality of pixel electrodes disposed in the respective pixel regions defined by the gate wires and the data wires; a plurality of first common electrodes which correspond to the pixel electrode portion, and which extend in the second direction; and a plurality of second common electrodes disposed among the first common electrodes. The display device separately drives the first common electrodes and the second common electrodes, thus driving the electrodes in a dot inversion system.
