Abstract

See full text

The present invention relates to an organic light emitting diode and a method of manufacturing the same. An organic light emitting diode according to the present invention comprises an exciton blocking layer comprising a compound represented by Formula 1 to confine an exciton to a light emitting layer to prevent light emitting leakage, and thus there is an effect of implementing an organic electroluminescence diode having excellent light emitting efficiency. Further, even though there is no separate electron injection layer, electron injection and light transport characteristics are excellent by comprising an electron transport layer comprising a compound represented by Formula 2 or 3, and thus it is possible to implement an organic light emitting diode having a simple and economical manufacturing process, a low voltage, high efficiency, and a long life span as compared to the related art.
