Abstract:
There is provided a method of manufacturing an organic EL display including an insulating substrate, a power supply terminal, a plurality of pixels arrayed on the substrate and each including an organic EL element and a pixel circuit, and an organic planarizing film covering the pixel circuits and interposed between the organic EL elements and the substrate, including selecting a pixel which can be recognized as a dark spot and/or a bright spot from the pixels, and irradiating, of the pixel circuit included in the selected pixel, a portion located between the organic planarizing film and the substrate with an energy beam through the substrate to electrically disconnect the organic EL element included in the selected pixel from the power supply terminal.
