ORGANIC ELECTROLUMINESCENT ELEMENT |
| 摘要 |
The present invention provides an organic electroluminescent element containing: a first gas barrier layer; an intermediate layer; a second gas barrier layer; a third gas barrier layer; a first electrode; an organic functional layer; and a second electrode, in that order, wherein the intermediate layer contains a resin and has a thickness of 10 μm to 250 μm; the second gas barrier layer contains silicon, carbon and oxygen, wherein a composition of silicon, carbon and oxygen contained in the second gas barrier layer is continuously changed in a thickness direction of the second gas barrier layer, and distribution curves of silicon, carbon and oxygen each have an extremum point; and the third gas barrier layer is a polysilazane reforming layer. |
