Abstract:
1. A method for manufacturing an electroluminescent element comprising: a process of forming a light emitting layer and a primary photoresist layer in this order, on a base substance; a process of pattern exposing and then developing the primary photoresist layer, so as to a part corresponding to a predetermined light emitting part of the primary photoresist layer remains; a process of forming a light emitting part surface which is covered with the primary photoresist layer and a light emitting end part surface not covered with the primary photoresist layer, by removing the light emitting layer which is bared because the primary photoresist layer is removed; a process of forming a secondary photoresist layer so as to avoid a contact between the light emitting part surface and a light emitting layer formed outside thereof, the light emitting end part surface and a light emitting layer formed outside thereof and to cover the light emitting part surface and the light emitting end part surface; and a process of pattern exposing and then developing the secondary photoresist layer, so as to avoid the contact between the light emitting part surface and the light emitting layer formed outside thereof, the light emitting end part surface and the light emitting layer formed outside thereof and not to bare the light emitting part surface and the light emitting end part surface from the secondary photoresist layer, wherein a plurality of kinds of light emitting parts are formed on the base substance by patterning light emitting layers of different kinds by a plurality of times by a photolithography method, on the base substance with an electrode layer formed.
