ABSTRACT:
A liquid crystal display comprises a plurality of first parallel electrodes arranged on a first plane, and a plurality of second parallel electrodes extending in a direction normal to the first parallel electrodes and arranged on a second plane spaced from the first plane. Between the first and second plane is a layer of twisted nematic liquid crystal. A matrix array of pixel electrodes are respectively arranged on the first plane at intersections of the first and second parallel electrodes. A matrix array of switching elements are associated respectively with the pixel electrodes. The switching elements are subdivided into groups which are associated respectively with the first parallel electrodes. Each switching element comprises a plurality of metal-insulator-metal laminated structures with the insulator having a nonlinear resistance characteristic. The metal-insulator-metal structures are series-connected between the associated first electrode and the associated pixel electrode for establishing a switched connection therebetween in response to a potential developed at an intersection of the first and second parallel electrodes.
