<P>PROBLEM TO BE SOLVED: To provide an organic electroluminescent element having high brightness and long life. <P>SOLUTION: In an organic electroluminescent element in which an organic EL layer having at least one luminous layer and a cathode electrode are formed on an anode electrode in the order, the organic EL layer comprises a hole injection layer, a hole transport layer, a luminous layer, an electron transport layer, an electron injection layer and a cathode electrode that are formed in the order, and main materials forming at least two continuous layers among the hole injection layer, the hole transport layer, and the luminous layer are same. In a method for manufacturing the organic electroluminescent element, the continuous two layers are manufactured while the main materials are supplied continuously and a supply amount of an additive material is controlled. <P>COPYRIGHT: (C)2012,JPO&INPIT |
