ABSTRACT:
An in-plane switching (IPS) mode liquid crystal display (LCD) device is described which does not contain a common electrode. In the IPS mode LCD device. In the IPS display device, a pixel is defined by gate lines and data lines that cross each other. One or more switching devices are formed at the pixel. First and second electrodes are disposed at the pixel. The first electrode is connected with one of the data lines through the switching device and the second electrode is connected with another of the data lines through another switching device. The other switching device is either formed at the pixel or formed at an adjacent pixel. The data lines, and thus the first and second electrodes, have different potentials applied thereto, thereby forming an electric field without using a common electrode.
