发明名称 Light emitting device including plural carbon-based thin film layers
摘要 When a light emitting element is actuated to allow the light emission, the generation of Joule heat occurs, leading to the decomposition or crystallization of an organic compound to cause the degradation of the light emitting device. Therefore, a light emitting element of the present invention is provided for effecting removing or decreasing the generation of heat. In the present invention, between two electrodes, layers having organic compounds and carbon-based thin films are alternatively laminated one after another for stepping down the driving voltage in the light emitting element using the tunnel effect. In addition, a carbon-based thin film is placed on a film containing an organic compound, so that it prevents the electric filed from being locally concentrated and also prevents the generation of short-circuit between the anode and the cathode.
