Abstract: A liquid crystal display device includes a liquid crystal display panel, two polarizing plates, and a backlight unit. A pixel included in the liquid crystal display panel is divided into a first domain and a second domain and includes a second electrode and a third electrode. The third electrode is insulated from and overlapped with the second electrode. First liquid crystals disposed in the first domain are twisted in a direction different from a direction in which the second liquid crystals disposed in the second domain are twisted. The liquid crystal display device selectively drives the second electrode and the third electrode, thereby controlling a viewing angle thereof.
