A pattern of transparent conductive material, such as tin oxide, is formed on a transparent vitreous substrate using a polycrystalline material, such as cadmium or zinc sulfide, to mask the substrate surface while depositing material forming the transparent conductive layer. The polycrystalline material and any overlying transparent conductive material are easily removed by a chemical etch, leaving the desired pattern of transparent conductive material adhering to the substrate. Two electrically conductive patterns may be formed in intersecting relationship and isolated, one from the other. The degree of electrical connection between the two patterns will be a function of the resistance of the polycrystalline material therebetween at points of crossing. In some instances, electroluminescence may be obtained by selecting the proper crystalline material wherein an electrical display may be created by selectively energizing crossing electrical conductors.
