Liquid crystal display device
DC CAFC
First Claim
1. A liquid crystal display device comprising:
- a first substrate panel and a second substrate panel;
a liquid crystal layer held between said first and second substrate panels;
a gate terminal, a gate wiring, a plurality of control electrodes, a drain terminal, and a drain wiring, being disposed on said first substrate panel;
a control electrode terminal in a condition independent of said gate wiring;
a terminal part including said control electrode terminal, said gate terminal and said drain terminal, said terminal part being arranged on at least first and second side portions of a surface of said first substrate panel; and
wherein said control electrode terminal is disposed on said first side portion of said terminal part with the gate terminal being disposed on said second side portion of the terminal part, and wherein each of said control electrodes is connected into a connected line that does not cross with the gate wiring, said connected line being arranged so as to extend to the second side portion of said terminal part.

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.
