A liquid crystal display device, in which each pixel region includes a plurality of first electrodes electrically connected to each other, a plurality of second electrodes electrically connected to each other and a plurality of third electrodes electrically connected to each other; the third electrodes are arranged in parallel with the second electrodes approximately and are electrically connected with the first electrodes; the first electrodes and the second electrodes are located in different layers respectively and there is an insulation layer therebetween; the first electrodes and the third electrodes intersect with each other to define a plurality of unit regions; there are two second electrodes passing through inside each unit region, and the first electrode between the two second electrodes is provided with a protrusion-shaped pattern in a position not overlapping with the second electrode. The LCD device has a wider viewing angle and lower operating voltage.
