Abstract: The disclosed method is for manufacturing organic EL displays that comprise a substrate and multiple organic EL elements that are disposed in a matrix form on said substrate, and wherein said organic EL elements comprise pixel electrodes that are disposed on said substrate, an organic layer that is disposed on said pixel electrodes and a counter-electrode that is disposed on said organic layer.

Abstract: Disclosed is a method for manufacturing an organic EL display, which comprises: a step of preparing an organic EL panel that comprises a substrate and organic EL elements arranged as a matrix on the substrate, wherein each organic EL element has a pixel electrode arranged on the substrate, an organic layer arranged on the pixel electrode, a transparent counter electrode arranged on the organic layer, a protective layer arranged on the transparent counter electrode, and a color filter arranged on the protective layer, and a defect portion present in the organic layer in each organic EL element is detected; a step of destroying a region of the transparent counter electrode positioned above the defect portion by irradiating the region with laser light through the color filter; and a step wherein a region of the color filter positioned above the defect portion is removed.

Abstract: Laser light is irradiated onto a foreign substance, which is contaminated into an organic layer of an organic EL element, to insulate the periphery of the foreign substance, thereby repairing a defect of the organic EL element that may be caused by the foreign substance. Before the laser light is irradiated onto a pixel containing a foreign substance, the laser light is irradiated onto peripheral pixels around the pixel containing the foreign substance, while shifting a focal position of laser light. The focal position of laser light is defined based on a laser irradiation mark and an emission state of the pixel. The laser light is irradiated with the adjusted focus to insulate a foreign substance section without damaging other portions than the periphery of the foreign substance, thereby making it possible to repair a defect that may be caused by the foreign substance.

Abstract: In a method of repairing an organic EL display, in which when a foreign particle has contaminated a pixel electrode to cause a defect during manufacture of an organic EL display, it is possible to repair the defect locally and simply without damaging the vicinity of the repaired part of the pixel electrode by the repair. In manufacture of the organic EL display, a defect due to a foreign particle is repaired by detecting the foreign particle that has contaminated the pixel electrode, lowering a fine needle having a hemispherically-shaped tip downward toward the foreign particle, and plastic deforming the foreign particle and part of the pixel electrode together to bury the foreign particle into the pixel electrode. A short circuit due to a foreign particle is prevented by pressing the foreign particle into the pixel electrode.
