ORGANIC COMPOUND AND ORGANIC LIGHT EMITTING DIODE AND ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE USING THE SAME

The present invention relates to an organic compound in which two amine groups are connected by biphenylene, and one or two substituents having a silyl group is or are connected to nitrogen atoms forming the amine groups. According to the present invention, the organic compound is excellent in hole injection properties, hole transport properties and/or electron blocking properties by comprising the amine groups. Further, the organic compound has improved light emitting efficiency compared to the case in which the substituent which does not have the silyl group, or has two or more silyl groups is connected to the nitrogen atoms. Therefore, when the organic compound of the present invention is applied to a hole layer, an electron blocking layer and/or a charge generation layer of an organic light emitting diode, light emitting efficiency is improved, and current density can be reduced. Accordingly, light emitting efficiency of the organic light emitting diode, to which the organic compound of the present invention is applied, can be greatly improved.COPYRIGHT KIPO 2018
