ORGANIC ELECTROLUMINESCENT ELEMENT AND METHOD FOR MANUFACTURING SAME |
摘要 |
<p>The problem to be solved by the present invention is to prolong the luminance half life of an organic EL element. A means for solving the problem is.a method for producing an organic electroluminescent element comprising a first electrode that is formed first, a second electrode that is formed later, and a light-emitting layer that is formed between the first electrode and the second electrode, the method comprising the steps of: applying a solution containing a light-emitting organic material to a surface of a layer located below to form an applied film; calcining the applied film in an inert gas atmosphere or in a vacuum atmosphere to form a light-emitting layer; holding the surrounding of the formed light-emitting layer in an inert gas atmosphere or in a vacuum atmosphere; and forming a layer located on the light-emitting layer in an inert gas atmosphere or in a vacuum atmosphere.</p> |
