An object of the invention is to provide an organic EL display apparatus using an organic EL device capable of light emission to a high luminance at a relatively low voltage so that the apparatus is prevented from erroneous light emission and a drop of contrast and features a high operating speed. The object is achieved by an organic EL display apparatus comprising a switching device comprising a controlling electrode and a set of controlled electrodes formed on a non-single-crystal silicon substrate, and an organic EL device adapted to be driven by the switching device and comprising a positive electrode, a negative electrode, and an organic layer between the electrodes participating in at least a light emitting function, the organic EL device further comprising a high resistance inorganic electron injecting and transporting layer between the organic layer and the negative electrode capable of blocking holes and having conduction paths for carrying electrons, or a high resistance inorganic hole injecting and transporting layer between the organic layer and the positive electrode capable of blocking electrons and having conduction paths for carrying holes, or both. <IMAGE> |
