ABSTRACT:
In the manufacture of display structures--including fluorescent material displays--by means of a print process, a base material (glass or plastic material), prior to the print process, is coated with an electrically conductive layer. During the print process, a strippable coating or pigmented lacquer having the shape of the structure, is deposited onto a first layer. After the print process, the non-printed electrically conductive layer is etched away and in the case of the non-fluorescent display structure, the strippable coating is peeled off the electrically conductive layer. The invention provides an improvement in the manufacture of display structures over the hitherto conventional photographic reproduction of silk-screen printing methods, and provides display structures having sharp edges to a thickness of approximately 10 .mu.m.
