Abstract
A liquid crystal display device includes a first substrate and a second substrate facing the first substrate. A liquid crystal layer is provided between the first and second substrates. First and second gate lines are extending in a first direction, and first and second drain lines are extending in a second direction. A pixel area is defined by the gate lines and drain lines. A counter electrode assigned to the pixel area and having a hollow portion is provided adjacent to a solid portion. The hollow and solid portions are extending in the second direction. One hollow portion is provided after N number of the solid portions, the N being a number equal to or greater than 3. A pixel electrode is assigned to the pixel area and is opposing the counter electrode. The pixel electrode has a connecting portion extending in the first direction and first and second extending portions extending in the second direction. The connection portion connects the first and second extending portions, wherein the first extending portion is vertically aligned to the hollow portion of the counter electrode and the second extending portion is vertically aligned to the solid portion of the counter electrode. An insulating layer is provided between the counter and pixel electrodes.
