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.
本发明涉及一种有机发光二极管及其制造方法。根据本发明的有机发光二极管包括由式 1 所代表的化合物组成的激子阻挡层,以将激子限制在发光层中,防止发光泄漏,从而实现具有优异发光效率的有机电致发光二极管的效果。此外,即使没有单独的电子注入层,但通过包含由式 2 或式 3 所代表的化合物组成的电子传输层,电子注入和光传输特性也非常出色,因此,与相关技术相比,可以实现制造工艺简单经济、低电压、高效率和长寿命的有机发光二极管。
