ORGANIC LIGHT-EMITTING DIODE

摘要

Disclosed in an aspect is an organic light emitting diode comprising a first electrode; a second electrode facing the first electrode; and a light emitting layer interposed between the first electrode and the second electrode, and including a dopant, a first host and a second host. Provided is the organic light emitting diode comprising the light emitting layer emitting blue delayed fluorescence having high efficiency and improved roll-off properties.
