An organic electroluminescence device includes an element substrate including a plurality of light-emitting elements each having an organic luminescent layer held between a pair of electrodes, a sealing substrate opposed to the element substrate, and a peripheral seal layer provided in the peripheral portion between the element substrate and the sealing substrate, for fixing the element substrate and the sealing substrate, wherein an electrode protecting layer covering the light-emitting elements, an organic buffer layer covering the electrode protecting layer, and a gas barrier layer covering the organic buffer layer are formed, the gas barrier layer is formed in a region wider than that of the organic buffer layer, the peripheral seal layer is provided on the gas barrier layer, and the peripheral edge of the organic buffer layer is disposed within the width of the peripheral seal layer
