Title:
ORGANIC LIGHT EMITTING DIODE
Document Type and Number:
WIPO Patent Application WO/2013/180503
Kind Code:
A1
Abstract:
The present specification relates to an organic light emitting diode, comprising: a first electrode; a second electrode; and two or more light emitting units provided between the first electrode and the second electrode, wherein a charge generating layer is formed between two adjacent light emitting units among the light emitting units, an electron transport layer is provided between the light emitting unit close to the first electrode of the two adjacent light emitting units and the charge generating layer. The electron transport layer comprises: a first electron transport layer doped with an n-type dopant; and a second electron transport layer doped with metal salt, a metal oxide or organic metal salt.
