摘要： Electroluminescent device means comprising a base substrate member having a plurality of individual electrically conductive drive lines arranged in integral rows upon the surface of said substrate, a film of an electroluminescent phosphor disposed on the surface of said rows of electrically conductive drive lines, a plurality of individual electrically conductive drive lines arranged in integral columns upon the surface of said phosphor and orthogonally overlying said rows at certain mutual junction areas; and means coupling a source of electrical energy to each of said electrically conductive drive lines in said rows and columns; said electrically conductive columns having isolated perforate openings formed therein at said junction areas, said openings having a large peripheral to area ratio and being disposed along said conductors in enclosed relationship therewithin.
