ABSTRACT:
A method of manufacturing an electroluminescence display device capable of displaying a predetermined number of characters comprising a bare chip, a groove for fittingly receiving the bare chip, and a vacuumized space for protecting the bare chip from external influences. Epoxy resin is applied to the lower periphery of the groove and the bare chip having approximately same size as the groove is received in and spaced from the bottom of the groove. By providing a panel lead at the same height as an Al electrode of the bare chip, ultrasonic bonding of an Al or Au wire to the panel lead and electrode is easily achieved.
