ABSTRACT:
The present publication describes a plate-shaped display structure, in particular an electroluminescent display structure. The structure comprises a frame, e.g. a rack-like frame, a printed-circuit plate fitted to and supported on the frame, wherein the printed-circuit plate is provided with first contact areas a display plate, preferably made of glass, which is fitted onto the printed-circuit plate at a distance from the latter and which is provided with second contact areas, a fastening structure for attaching the display plate and the printed-circuit plate to each other, and connecting conductors, which interconnect the first and the second contact areas. According to the invention, the fastening structure comprises a so-called two-sided resilient tape, provided intermediate the printed-circuit plate and the display plate to cause those two plates to adhere to each other, and the display plate and the frame are dimensioned in such a way that they do not reach contact with each other. By means of the invention, it is easy to provide a resilient attachment of a fragile EL glass to the frame structure, wherein the EL glass has a plane fastening face and, at the same time, to maintain precise alignment relative the printed-circuit plate, from which the control signals for the EL glass come.
