PROBLEM TO BE SOLVED: To enhance the utilization efficiency of a material for forming an organic EL layer and for forming a uniform organic film over a wide area, in an electroluminescent element having the organic EL layer. SOLUTION: An anode electrode 2, a hole transport layer 3, a light-emitting layer 4, and a cathode electrode 5 are formed on a transparent substrate 1. The hole transport layer 3 and the light-emitting layer 4 are formed through electrodepostion method. The utilization efficiency of the materials for forming the hole transport layer 3 and the light-emitting layer 4 can be enhanced, as compared with the case of formation by over vapor deposition method, and the uniform organic film can be formed over a wide area.
