PROBLEM TO BE SOLVED: To obtain an org. electroluminescent element which is suitable as a polysilane-based planar ultraviolet light source stably emitting light at room temp. by using a thin polydimethylsilane film as the luminescent layer. SOLUTION: This element has at least a luminescent layer between a pair of electrodes and the luminescent layer comprisies a thin polysilane film represented by the formula: [(CH3 )2 Si]n . (wherein n is 5 to about 10,000). The luminescent layer is formed by a dry method such as vapor deposition, sputtering, or laser ablation. The thickness of the film is pref. about 500-10,000Å. The luminescent layer may contain a compd. having a hole transpot capability and a compd. having an electron transport capability each in an amt. of up to about 30wt.%.
