Abstract:
A light emitting device having high definition, a high aperture ratio, and high reliability is provided. The present invention achieves high definition and a high aperture ratio with a full color flat panel display using red, green, and blue color emission light by intentionally forming laminate portions, wherein portions of different organic compound layers of adjacent light emitting elements overlap with each other, without depending upon the method of forming the organic compound layers or the film formation precision.
