摘要： An organic light emitting diode (OLED) in which at least one emitting material layer includes a dopant having the structure represented by Formula 1 and a biscarbazole-base host and an azine-based host, and an organic light emitting device including the OLED. The OLED and the organic light emitting device including the hosts and the dopant can improve their luminous efficiency and luminous lifespan.

摘要： An organic light emitting diode (OLED) (D, Dl, D2, D3) in which at least one emitting material layer (340, 740, 740') includes a dopant (342, 742) having the following structure represented by Formula 1 and a biscarbazole-base host (344, 744) and/or an azine-based host (346, 746), and an organic light emitting device (100, 400) including the OLED (D, Dl, D2, D3). The OLED (D, Dl, D2, D3) and the organic light emitting device (100, 400) including the host (344, 744, 346, 746) and the dopant (342, 742) can improve their luminous efficiency and luminous lifespan.
