Abstract
Light is prevented from being emitted from a region that overlaps a contract hole in a structure in which light emitting devices are stacked. A stacked organic electro-luminescent display apparatus includes a contact hole that electrically connects a first electrode or a second electrode to a driving circuit. The first or second electrode and a second organic compound layer are provided in the contact hole, and the second organic compound layer existing in the contact hole does not emit light.
