ORGANIC ELECTROLUMINESCENCE ELEMENT, METHOD FOR MANUFACTURING ORGANIC ELECTROLUMINESCENCE ELEMENT, ILLUMINATING DEVICE AND DISPLAY DEVICE

摘要

Provided are an organic electroluminescence element having high light emitting efficiency and a long life, a method for manufacturing the organic electroluminescence element, an illuminating device and a display device. The organic electroluminescence element is provided with at least an anode and a cathode on a supporting substrate, and an organic layer containing at least one layer of a reactive organic compound between the anode and the cathode.The organic electroluminescence element is characterized in that the concentration of the reactive organic compound in the organic layer is not uniform at one time between the end of the manufacturing process and start of carrying electricity.
