A liquid crystal display device capable of controlling a viewing angle is disclosed. The liquid crystal display device includes: a liquid crystal panel configured to include a plurality of quad type pixels each consisted of red, green, blue, and viewing angle control sub-pixels; and a timing controller configured to reply to a viewing angle mode selected by a user and apply red, green, and blue data and any one of a wide viewing angle control data, a first narrow viewing angle control data, and a second narrow viewing angle control data to the liquid crystal panel. As such, the LCD device controls a range of viewing angles, thereby allowing the image to be viewed from every direction or not to be viewed from the left and right directions or the upward diagonal directions in the center of the user. In other words, the LCD device can limit the image display according to the positions of the persons adjacent to the user. Therefore, the user using the LCD device can adjust it to freely share information or to limit its range with adjacent persons. Furthermore, the LCD device can enhance information reliability and security.
