ABSTRACT:
The main object of the present invention is to provide a method for producing an EL element for realizing the high luminous efficiency, the high light takeout efficiency, the simplicity of the production process, and the formation of highly fine patterns. In order to achieve the above-mentioned object, the present invention provides a method for producing an EL element wherein at least one organic EL layer constituting the EL element is patterned by the use of a photolithography method.
