Title:

ORGANIC ELECTROLUMINESCENT DEVICE EMPLOYING ORGANIC LIGHT EMITTING COMPOUND AS LIGHT EMITTING MATERIAL

Document Type and Number:

WIPO Patent Application WO/2012/015274

Kind Code:

A3

Abstract:

The present invention relates to an organic electroluminescent device which shows an effective host-dopant energy transfer mechanism and thus shows highly efficient luminous characteristics on the basis of an improved electron density distribution. In addition, the present invention overcomes the problems of the conventional materials such as the deterioration of initial efficiency, low lifetime characteristics and the like, and can obtain high performance luminous characteristics including high efficiency and a long lifetime from each color.
