ABSTRACT:
A method of fabricating an active matrix display device having a matrix of display elements (12), particularly liquid crystal elements. An array of first electrodes (24) are connected to associated address conductors (20) through two-terminal non-linear devices (16), in which the first electrodes and address conductors are provided as separate planar arrays. Prefabricated, physically discrete non-linear devices (35), such as MIMs or punch through diodes, are arranged between the planar arrays electrically coupling respective first electrodes to associated address conductors. A set of display element second electrodes/address conductors (18) is provided as a further array spaced from the array of first electrodes with liquid crystal material (21, 61) disposed therebetween. The non-linear devices are distributed, possibly carried in a polymer film, in a quasi-random manner. Large area displays are possible without using extensive lithography.
