Abstract: In a luminescent display, when a shortcircuit between the transparent electrode 102 and the metal electrode 104 occurs and a defective pixel such as a pixel which does not luminesce or a luminescence-defective pixel is formed, repairing is performed so as to remove only a part B corresponding to the defective part, in the metal electrode 104 corresponding to the region which corresponds to the defective part, and in which the transparent electrode 102 and the metal electrode 104 intersect with each other. Therefore, a current flow between the metal electrode 104 and the transparent electrode 102 which face each other via an organic layer 103 is allowed by the metal electrode 104 in the remaining part A, thereby enabling the pixel and the subsequently scanned pixels to luminesce. The corresponding part of the metal electrode 104 is removed away by irradiating the part with a laser beam.

Abstract: A new organic EL display panel comprises transparent electrodes 2, an insulating layer 7, an organic luminous layer 4 and backside electrodes 5 successively laid on a transparent substrate 1. The insulating layer 7 is converted from a positive novolac, negative cyclized rubber or chemical amplified photoresist layer shaped to a grate pattern, by baking treatment to remove water and a solvent from the photoresist layer. Electric resistance of the insulating layer 7 is good enough to inhibit leakage of an electric current between the electrodes 2 and 5. The EL display panel reproduces a distinct image over a long term without growth of dark spots.
