Abstract

For a flat display device, a control subassembly is needed which consists of two control plates (1;7) each formed by a layer of parallel conductors (2;8) which are isolated from each other. During the manufacture of the control subassembly, the first control plate is provided with a glass frit in the form of continuous strips (10) perpendicular to the conductors. The glass frit is set, and the application of the strips is repeated. The second control plate is then put on the first control plate in such a way that their conductors are mutually perpendicular. After that, the glass frit is crystallized.
