MP1344-PCT Abstract of the Disclosure A liquid crystal display comprises (a) a first transparent base; (b) a plurality of first picture electrodes on the first transparent base; (c) a plurality of data lines for supplying electrical signals to the first picture electrodes; (d) a second transparent base, parallel to and spaced apart from the first transparent base; (e) a plurality of second picture electrodes on the second transparent base; (f) a plurality of varistor elements made of a varistor material comprising zinc oxide as a primary metal oxide and cobalt and praseodymium oxides as additive metal oxides, in amounts of between 0.1 and 8.0 atom % cobalt and between 0.08 and 8.0 atom % praseodymium, one varistor element being associated with and in electrical contact each second picture electrode; (g) a plurality of scan lines for supplying electrical signals to the second picture electrodes via the respective associated varistor respective and (h) electrooptically active liquid crystal material between the first and second picture electrodes. In a preferred embodiment, the plurality of varistor elements is in the form of a varistor array comprising an integral body of varistor material having two major opposing faces, one of the opposing faces having an array of indentations thereon, each indentation defining a varistor element.
