PROBLEM TO BE SOLVED: To provide a flexible light emitting device having an OLED formed on a plastic substrate enabled to restrain deterioration caused by the diffusion of impurities such as water, oxygen, alkali metal, alkali earth metal. SOLUTION: Not less than two layers of barrier film shown as AlXOY preventing an organic light emitting layer of an OLED from the intrusion of oxygen and water, and preventing an active layer of TFT from the intrusion of alkali metal or alkali earth metal or the like, are formed, further, a stress releasing film containing resin is formed between the two layers of barrier film.
