ORGANIC ELECTRO-LUMINESCENCE ELEMENT, IMAGE FORMING DEVICE USING THE ELEMENT, AND PORTABLE TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide an organic electro-luminescence element and an image forming device having an excellent visibility and capable of maintaining a highly efficient light emitting performance, and a portable terminal low in weight and long in usable time. SOLUTION: This organic electro-luminescence element comprises an anode for filling holes, a light emitting layer having a light emitting area, and a cathode for filling electrons installed on a substrate. Light radiated from the light emitting layer is extracted from a surface opposite to the substrate, and an inverse V-shaped structure higher than the light emitting layer is formed on at least a part of the element forming surface of the substrate.
