Patent ID: 7615388

Claim:
A method for producing an electroluminescent element, wherein at least a buffer layer and a luminous layer out of a plurality of electroluminescent layers constituting an electroluminescent element are patterned by a use of a photolithography method; and the method comprises a process of forming a patterned buffer layer in which the buffer layer is insoluble in a photoresist solvent, a photoresist peeling liquid and a solvent to be used for forming the luminous layer and patterned by the use of a photoresist that is insoluble in a solvent to be used for forming the buffer layer, and a process of forming a patterned luminous layer on the patterned buffer layer in which the luminous layer is insoluble in the photoresist solvent, a photoresist developing solution, and the photoresist peeling liquid and patterned by the use of a photoresist that is insoluble in a solvent to be used for forming the luminous layer.
