Abstract
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.
