Original Abstract Submitted

an organic light emitting diode (oled) is described, as well as a display device, e.g., a display device or a lighting device that includes the oled. the oled includes a first electron transport layer having a first electron transporting material of a benzimidazole-based compound substituted with at least one anthracenyl group, and a second electron transport layer having a second electron transporting material of a benzimidazole-based compound substituted with at least one fluorenyl group having a spiro structure. an electron injection layer and/or a charge generation layer includes a phenanthroline-based compound. the second electron transport has an electron transport material with excellent thermal stability, disposed adjacently to the electron injection layer and/or the charge generation layer, so that the oled can maintain good luminescent intensity in an environment of high temperature and implement beneficial luminous properties.
