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.
