Abstract: An organic light emitting device including a plurality of organic layers between a first electrode and an emitting layer, wherein the organic layer includes an electron blocking layer. In one embodiment, a first organic layer, an electron blocking layer, a second organic layer and an emitting layer are formed on the first electrode. The electron blocking layer has a Lowest Unoccupied Molecular Orbital (LUMO) level which is lower than that of the first organic layer. Thus, the electron blocking layer traps excess electrons injected from the emitting layer, thereby improving lifetime characteristics of the OLED.
Abstract translation: 一种在第一电极和发光层之间包括多个有机层的有机发光器件，其中所述有机层包括电子阻挡层。 在一个实施例中，在第一电极上形成第一有机层，电子阻挡层，第二有机层和发光层。 电子阻挡层具有低于第一有机层的最低未占分子轨道（LUMO）水平。 因此，电子阻挡层捕获从发光层注入的过量电子，从而改善OLED的寿命特性。
