Abstract: A liquid crystal display comprises (a) a first transparent base (26); (b) a plurality of first picture electrodes (28) on the first transparent base; (c) a plurality of data lines (29) for supplying electrical signals to the first picture electrodes; (d) a second transparent base (27), parallel to and spaced apart from the first transparent base; (e) a plurality of second picture electrodes (30) on the second transparent base; (f) a plurality of varistor elements (37) made of a varistor material comprising zinc oxide as a primary metal oxide and cobalt and praseodymium oxides as an 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 (42) for supplying electrical signals to the second picture electrodes via the respective associated varistor elements; and (h) electrooptically active liquid crystal material (25) 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 (35) having two major opposing faces, one of the opposing faces having an array of indentations thereon, each indentation defining a varistor element.
