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.
