PROBLEM TO BE SOLVED: To obtain an organic EL element provided with a color conversion mode, which enables to relatively inexpensively obtain light with a desired color without unnecessarily complicating the structure of an organic light-emitting layer, while having a light extraction structure for highly efficiently extracting light-emission of the organic light-emitting layer to the outside of the organic EL element. SOLUTION: The organic EL element having a microstructure includes a transparent substrate, which has a microstructure layer on at least either one of its surfaces, a transparent electrode formed on the transparent substrate, and an organic light-emitting layer formed on the transparent electrode while including a light-emitting layer that emits light. At least one microstructure layer is composed so that a fluorescent material is almost uniformly dispersed in the microstructure. COPYRIGHT: (C)2008,JPO&INPIT
