ABSTRACT:
A light emitting element having an organic compound, which can be extended its longevity is provided. According to the present invention, there is provided a constitution in which, in order to protect a light emitting element from moisture, an inorganic insulating film312a, a stress relaxation layer312bhaving transparency and a hygroscopic property, and an inorganic insulating film312care repeatedly laminated over a cathode. The stress relaxation layer312bhaving transparency and the hygroscopic property uses at least one film selected from the group consisting of a film comprising a same material as that of a layer310, containing an organic compound, sandwiched between a cathode and an anode, a layer capable of being formed by vapor deposition, and a layer capable of being formed by coating.
