Abstract

一种有机发光二极管及显示面板，该有机发光二极管包括：第一电极(10)、第二电极(20)、发光层(14)、空穴阻挡层(15)和电子传输层(16)；第一电极(10)与第二电极(20)相对设置；发光层(14)位于第一电极(10)与第二电极(20)之间；空穴阻挡层(15)位于发光层(14)与第二电极(20)之间；电子传输层(16)位于空穴传输层(15)和第二电极(20)之间，其中，空穴阻挡层(15)的HOMO能级与发光层(14)的HOMO能级的能级差值大于等于0.1eV，电子传输层(16)的HOMO能级与空穴阻挡层(15)的HOMO能级的能级差值大于等于0.1eV，由此，所述有机发光二极管的空穴阻挡层(15)和电子传输层(16)可有效阻挡空穴由发光层(14)传输至第二电极(20)侧，而是将空穴有利地限制在发光层(14)中，从而可提升发光层(14)中电子和空穴的数量，使较多的电子和空穴在发光层中复合，从而可提升有机发光二极管的发光效率。
