Abstract
A matrix wiring substrate comprises a plurality of first level wirings provided on an insulating substrate, a plurality of second level wirings provided on the insulating substrate to intersect the first level wirings, and an insulating layer provided between the first and second level wirings so as to electrically separate the first and second level wirings from each other. A common electrode is connected in common to the first and second level wirings for prevention of an electrostatic destruction of the insulating layer. A non-linear resistance element is connected between each of the first and second level wirings and the common electrode. The non-linear resistance element has a resistance non-linearly decreasing with increase of a voltage applied across the non-linear resistance element.
