有机发光装置
摘要：
本申请涉及有机发光装置。该有机发光装置包括正极、负极以及在所述正极与所述负极之间的至少一层有机材料层。所述至少一层有机材料层包括空穴注入层、空穴传输层、发射层、电子传输层和电子注入层，并且所述发射层包含主体材料和掺杂剂材料。此外，包含双极性化合物的寿命提高层布置在所述发射层与所述电子传输层之间。
摘要（英）：

An organic light-emitting device includes a positive electrode, a negative electrode and at least one organic material layer between the positive electrode and the negative electrode. The at least one organic material layer includes a hole-injecting layer, a hole-transporting layer, an emission layer, an electron-transporting layer, and an electron-injecting layer, and the emission layer includes a host material and a dopant material. In addition, a lifetime enhancement layer including a bipolar compound is positioned between the emission layer and the electron-transporting layer.
