PROBLEM TO BE SOLVED: To provide an electroluminescent assembly using boron chelate for an 8-amino quinoline derivative. SOLUTION: A substrate, a positive electrode, an electroluminescent element and a negative electrode are included and at least, one of the two electrodes passes through a visible spectrum zone. In addition, the electroluminescent element contains one or more zones selected from a group of a hole injection zone, a hole transport zone, an electroluminescent zone, an electron transport zone and an electron injection zone respectively in order. Also, an electroluminescent assembly where each of the present zones can accept others of the aforementioned zone functions is made to contain the boric acid complex of an 8-amino quinoline derivative.
