Organic electroluminescent element, method for manufacturing same, and organic electroluminescent display device
Abstract:
An organic EL element (1) according to the present invention is such that a positive and negative charge transport layer (30) is interposed between a cathode (20) and an anode (10). The positive and negative charge transport layer (30) is composed of a single host material and has a light-emitting region (33) which is doped with a light-emitting dopant. The positive and negative charge transport layer (30) further has at least one of the following blocking regions: an electron blocking region (32), provided closer to the anode (10) than the light-emitting region (33), having a lowest unoccupied molecular orbital lower than that of the lowest unoccupied molecular orbital of the light-emitting region (33); and a hole blocking region (34), provided closer to the cathode (20) than the light-emitting region (33), having a highest occupied molecular orbital higher than that of the highest occupied molecular orbital of the light-emitting region (33).
Abstract(Chinese):

根据本发明的有机EL元件（1）使得正极和负电荷输送层（30）插入在阴极（20）和阳极（10）之间。 正极和负极电荷输送层（30）由单个主体材料构成，并且具有掺杂有发光掺杂剂的发光区域（33）。 正和负电荷输送层（30）还具有以下阻挡区域中的至少一个：比发光区域（33）更靠近阳极（10）设置的电子阻挡区域（32），具有最低 未占用的分子轨道低于发光区域（33）的最低未占分子轨道的分子轨道; 以及比发光区域（33）更靠近阴极（20）设置的具有比发光区域（33）的最高占位分子轨道高的占位分子轨道的空穴阻挡区域（34） ）。
