Abstract
In an active matrix type light emitting device, an upper surface injection type light emitting device in which an anode formed on the upper portion of the organic compound layer becomes an electrode for taking out the light is provided. In a light emitting element consisting of an cathode, an organic compound layer and an anode, it is characterized in that a protector is formed on the interface between the anode being an electrode for taking out the light and the organic compound layer. Noted that the protector formed on the organic compound layer has a transmittance of 70-100%, and the damage given to the organic compound layer when the anode is formed by a sputtering method can be prevented.
