A process of producing an electroluminescent element is provided. The
production process comprises repeating at least twice a step of forming
an electroluminescent layer comprising a buffer layer and a luminescent
layer by patterning using a photolithographic process, thereby producing
an electroluminescent element comprising a patterned electroluminescent
layer. The method includes the steps of forming a first pattern part
comprising a first buffer layer as the lowermost layer, and coating a
solution for forming a second buffer layer in a region including the
first pattern part. The first buffer layer is immiscible with the
solution for forming the second buffer layer.
