ABSTRACT:
In order to emit light from the upper side of a substrate, for example, a treatment is required such that a cathode is thinned. Generally, when light produced in a light emitting layer is passed through the electrode, brightness of a light emitting device is decreased. In the light emitting device of the present invention, an anode and a cathode are located so as to produce an electric field in a direction parallel with the surface of a substrate. Thus, light produced in the light emitting layer is emitted from the lower side or the upper side of the substrate without passing through the electrode.
