Abstract:
According to one embodiment, an organic semiconductor device includes a supporting substrate, a plurality of organic EL light emitting elements, a first barrier layer, a flattening layer, and a second barrier layer. The flattening layer exists sporadically and makes gentle in inclination steep elevation change present in the surface of the first barrier layer. The first barrier layer and the second barrier layer are made of moisture penetration preventive material.
