ORGANIC ELECTROLUMINESCENT ELEMENT |
摘要 |
<p>An organic electroluminescence device includes a plurality of organic semiconductor layers including an organic light-emitting layer and layered or disposed between a pair of anode and cathode opposed to each other. The device includes n-type-dopant-containing electron transport layer disposed between the cathode and the organic light-emitting layer. The n-type-dopant-containing electron transport layer includes an organic compound capable of transporting electrons as a first component which mixed with an n-type dopant of an electron donor of metallic atom or ion thereof as a second component. The organic electroluminescence device further includes an n-type-dopant blocking layer having an interface contacting with the n-type-dopant-containing electron transport layer to block the n-type dopant. The n-type-dopant blocking layer includes a heavy atom compound including at least one kind of heavy atoms with an atomic weight of 79 or more.</p> |
