[It is an object] to provide an organic electroluminescent element having a transparent electrode, with which there is no need to produce a separate light extraction layer, [which can be produced by] a simple film formation process, and which is advantageous in terms of cost. [This is] an organic electroluminescent element in which a substrate, a first transparent electrode that is adjacent to this substrate, an organic layer including at least one organic light-emitting layer, a second transparent electrode, a low refractive-index layer with a refractive index of 1.3 or less, and a reflector layer are formed in this order, with this organic electroluminescent element being such that the aforementioned first transparent electrode contains at least one type of transparent particle with a primary particle size of 0.5 &#x3bc;m or more.

Organic electroluminescent devices

The present invention provides a charge transport film which is prepared through subjecting a coating film including at least one charge transporting agent to an atmospheric pressure plasma treatment, wherein electron transfer between the charge transport film and a substance that contacts with the charge transport film is promoted, and deterioration in performance due to diffusion and mixing or crystallization of low molecular weight components, such as a charge transporting agent, incorporated in a cured film is suppressed also in the case of film formation by a wet method, and which exhibits excellent charge transportability and stability over time; a production method with good productivity; and a light-emitting element and photoelectric conversion element equipped with the charge transport film, the atmospheric pressure plasma treatment being preferably a treatment that applies plasma, which is generated using a plasma generating apparatus and conveyed using an inert gas, to the coating film.
