Abstract
A method for manufacturing an organic electro-luminescent (EL) element includes: a first process of preparing an organic EL element which includes a positive electrode, an organic layer which includes a light-emitting layer, and a negative electrode, the organic EL element having a short-circuited portion where the positive electrode and the negative electrode are short-circuited; and a second process of emitting femtosecond laser light to at least one of: the transparent electrically conductive material layer and the metal layer in a short-circuited portion; and the transparent electrically conductive material layer and the metal layer around the short-circuited portion to bring the transparent electrically conductive material layer and the metal layer into high-resistance states.
