ABSTRACT:
A thin film electroluminescent display is capable of effectively preventing dielectric breakdown between both electrodes. A first transparent electrode layer, a first dielectric layer, a luminescent layer, a second dielectric layer, and a second transparent electrode layer are laminated in that order on a first glass substrate to form a first light-emitting element. A second light-emitting element is fabricated in substantially the same way. A voltage is applied between the first and second electrode layers to cause the luminescent layers between both electrode layers to emit. As a result, desired characters are displayed. Those corners of the first and second electrodes disposed opposite to each other which are located within the planes of the electrode layers have round portions. The radius of circle of these round portions is in excess of a given value. This prevents concentration of the electric field on the corners of the electrodes.
