ORGANIC ELECTROLUMINESCENT ELEMENT, METHOD FOR PRODUCING SAME, AND DEVICE FOR PRODUCING SAME

摘要

Problems to be solved of the present invention are to provide a method for producing an organic electroluminescent device capable of producing an organic electroluminescent device having long lifetime, an organic electroluminescent device having long lifetime, a planar light source, an illumination apparatus and a display apparatus each having long lifetime. Means for solving the problem is a method for producing an organic electroluminescent device comprising a first electrode, a second electrode and a light emitting layer arranged between the first and second electrodes, the light emitting layer containing an organic film, the method comprising a step of applying a solution containing an organic compound onto the surface of a layer which is to be located just below the light emitting layer, to form the organic film in a dark place.
