Light emitting device and electronic apparatus

摘要

A light emitting device which is capable of suppressing deterioration by diffusion of impurities such as moisture, oxygen, alkaline metal and alkaline earth metal, and concretely, a flexible light emitting device which has light emitting element formed on a plastic substrate. On the plastic substrate, disposed are two layers and more of barrier films comprising a layer represented by AlNxOy which is capable of blocking intrusion of moisture and oxygen in a light emitting layer and blocking intrusion of impurities such as an alkaline metal and an alkaline earth metal in an active layer of TFT, and further, a stress relaxation film containing resin is disposed between two layers of barrier films.
