Abstract
A method for manufacturing an electro luminescent element includes a process of forming a light emitting layer and a photoresist layer in this order, on the base substance; a process of pattern exposing and then developing the photoresist layer, so as to the part corresponding to a predetermined light emitting part of the photoresist layer remains; a process of forming a light emitting part which its surface is covered with the photoresist layer, by removing the light emitting layer which is bared because the photoresist layer is removed; a process of forming a photoresist layer on the base substance, so as to cover the light emitting part; and a process of pattern exposing and then developing the photoresist layer, so as not to bare the light emitting part and the end part thereof.
