Patent ID: 7534557

Claim:
A method for manufacturing an electroluminescent element comprising: a first light emitting layer forming process of forming a first light emitting layer on a substrate on which at least an electrode layer is formed in a pattern; a first peeling layer forming process of forming a first peeling layer on the first light emitting layer; a first photoresist layer forming process of forming a first photoresist layer on the first peeling layer; a first photoresist layer patterning process of patterning, by exposing and developing first photoresist layer, so that the first photoresist layer remains only in an area where a first light emitting part will be formed; a first light emitting layer developing process of removing the first light emitting layer in part where the first photoresist layer is removed; a second light emitting layer forming process of forming a second light emitting layer on a substrate on which at least the first light emitting part, formed by laminating the first peeling layer and the first photoresist layer in this order, on a surface; a second peeling layer forming process of forming a second peeling layer on the second light emitting layer; a second photoresist layer forming process of forming a second photoresist layer on the second peeling layer; a second photoresist layer patterning process of patterning, by exposing and developing the second photoresist layer, so that the second photoresist layer remains only in an area where a second light emitting part will be formed; a second light emitting layer developing process of removing the second light emitting layer in a part where the second photoresist layer is removed; a third light emitting layer forming process of forming a third emitting layer on a substrate on which at least the first light emitting part, formed by laminating the first peeling layer and the first photoresist layer in this order, on a surface, and the second light emitting part, formed by laminating the second peeling layer and the second photoresist layer in this order, on the surface; a third peeling layer forming process of forming a third peeling layer on the third light emitting layer; a third photoresist layer of forming process of forming a third photoresist layer on the third peeling layer; a third photoresist layer patterning process of patterning, by exposing and developing the third photoresist layer, so that the third photoresist layer remains only in an area where a third light emitting part will be formed; a third light emitting layer developing process of removing the third light emitting layer in a part where the third photoresist layer is removed; and a peeling layer peeling process of removing each of the photoresist layer laminated thereon by peeling off each of the peeling layer.
