Abstract
An EL display is provided with enhanced light emission characteristics wherein light emitted from a light-emitting layer undergoes constructive interference due to a resonance effect. The EL display includes a transparent substrate, an anode and a cathode formed on the same side of the transparent substrate, and an intermediate layer interposed between the anode and the cathode, and said intermediate layer including a light-emitting layer that emits light when the anode and the cathode are electrically driven by a voltage, and wherein the anode and the cathode are formed as a translucent conductive layer that partially reflects the light emitted from the light-emitting layer.
