A light emitting device having a high definition, a high aperture ratio and a high reliability is provided. The present invention realizes a high definition and a high aperture ratio for a flat panel display of full colors using luminescent colors of red, green and blue without being dependent upon the film formation method and deposition precision of an organic compound layer by forming the laminated sections 21, 22 by means of intentionally and partially overlapping different organic compound layers of adjacent light emitting elements. Moreover, the protective film 32a containing hydrogen is formed and the drawback in the organic compound layer is terminated with hydrogen, thereby realizing the enhancement of the brightness and the reliability.
