ABSTRACT:
At least one light-absorption layer is disposed between a thin electroluminescent film and a counter electrode for absorbing light applied through a transparent electrode. According to the light-absorption layer, less light is reflected by the counter electrode, thereby preventing a visual contrast provided by electroluminescence from lowering owing to the reflected light. A plurality of light-absorption layers may be formed in the same arrangement. Materials useful for the light-absorption layers are Al.sub.2 O.sub.3, Al.sub.2 O.sub.3-x, Mo, Zr, Ti, Y, Ta, Ni, Al or the like with a thickness of about 10-300 A.
