Abstract
When any of pixels is not lit in an organic EL display having an organic EL layer between a first electrode and a second electrode, an organic layer of the pixel is observed. If the organic layer of the pixel contains foreign matter, the second electrode is separated into a region in contact with the foreign matter and a region not in contact with both the contact region and the foreign matter. Thus, not-lit display regions are reduced as less as possible, making it possible to manufacture an organic EL display excellent in display performance.
