Abstract
In a luminescent display, when a shortcircuit between the transparent electrode and the metal electrode 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 corresponding to the region which corresponds to the defective part, and in which the transparent electrode and the metal electrode intersect with each other. Therefore, a current flow between the metal electrode and the transparent electrode which face each other via an organic layer is allowed by the metal electrode in the remaining part A, thereby enabling the pixel and the subsequently scanned pixels to luminesce. The corresponding part of the metal electrode is removed away by irradiating the part with a laser beam.
