Abstract
A liquid crystal layer is sandwiched between two substrates of glass or the like and a gate terminal, a gate wiring, a control electrode and a drain terminal are arranged on the liquid crystal layer. The liquid crystal display device further has a control electrode terminal of the control electrode which is in an independent condition without crossing the gate wiring. A terminal part including this control electrode terminal and the gate terminal as well as the drain terminal is arranged on the outer side of the substrate panel. According to this construction, an arbitrary voltage can be applied to the control electrode so that the diagonal electrical field, which is necessary for the orientation division, can be set optimum in the intensity. Thereby the orientation division can be carried out properly. In addition, since there is no overlapping between the control electrode, including wiring and terminals, and the gate wiring, the short circuit problem can be alleviated to create good manufacturing yield of the liquid crystal display device.
