ABSTRACT:
In an electroluminescent panel comprising a transparent electrode, a back electrode, an electroluminescent layer between the transparent and the back electrodes, and a light absorption layer between the electroluminescent layer and the back electrode, the light absorption layer comprises a lower-order oxide of germanium and has a light absorption coefficient which is not smaller than 3.3.times.10.sup.-4 cm.sup.-1. The light absorption coefficient may be discretely or continuously increased from an electroluminescent layer side towards a back electrode side. The light absorption layer may be selectively deposited under the back electrode when it has a low resistivity.
