Summary:PROBLEM TO BE SOLVED: To provide a bendable organic EL display device excellent in reliability.SOLUTION: An organic EL display device has, in a pixel, an organic EL layer 111 sandwiched by a lower electrode 109 and an upper electrode 112. The organic EL display device is provided with a first inorganic protective film 113 covering the upper electrode 112. The first inorganic protective film 113 has a circular shape or a pentagonal or higher polygonal shape in a plan view.SELECTED DRAWING: Figure 1 【課題】信頼性の高い、湾曲可能な有機ＥＬ表示装置を実現する。【解決手段】画素内に、下部電極１０９と上部電極１１２に挟持された有機ＥＬ層１１１を有する有機ＥＬ表示装置であって、前記上部電極１１２を覆って第１無機保護膜１１３が形成され、前記第１の第１無機保護膜１１３は平面で視て円形または５角形以上の多角形であることを特徴とする有機ＥＬ表示装置。【選択図】図１
