METHOD FOR MANUFACTURING ORGANIC ELECTROLUMINESCENCE ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a photoelectronic device with good efficiency.

SOLUTION: An electroluminescence element has a first to a n-th (n is an integer of two or more) functional organic thin film layers emitting light by feeding electric current between an anode and a cathode, and a first to a k-th (k is an integer of 1≤k≤(n-1)) conductive thin film layers. The functional organic thin film layers and conductive thin film layers are alternately laminated in the electroluminescence element. The first functional organic thin film layer contacts the anode, and the n-th functional organic thin film layer contacts the cathode. The conductive thin film layers are in a cluster state and have a first layer including a p-type semiconductor and a Lewis acid, and a second layer provided closer to the anode side than the first layer and including an N-type semiconductor and an alkaline metal or an alkaline earth metal.
