Abstract
Official abstract text for this publication.
Provided are an organic light emitting diode and a method of manufacturing the same. The organic light emitting diode adjusts an optical resonance thickness and prevents spectrum distortions without use of an auxiliary layer. The organic light emitting diode includes a first electrode that is optically reflective; a second electrode that is optically transmissible and faces the first electrode; an organic emission layer interposed between the first electrode and the second electrode, the organic emission layer including: a first emission layer including a mixed layer that contains a host material and a dopant material, and a second emission layer comprising only the host material; and a carrier injection transport layer interposed between the organic emission layer and the first electrode or between the organic emission layer and the second electrode.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic light emitting diode comprising: a first electrode that is optically reflective; a second electrode that is optically transmissible and faces the first electrode; an organic emission layer interposed between the first electrode and the second electrode, the organic emission layer comprising: at least two first emission layers each comprising a mixed layer that contains a host material and a same dopant material, and at least one second emis…
