An organic electroluminescent element provided with a Hall transport layer of a structure in which a hole transport material is dispersed in a binder resin of a glass transition temperature Tg of not lower than 170 °C. Since the hole transport layer of the organic electroluminescent element has both a high durability and a high hole transport capacity, this element has excellent luminous efficiency, luminous brightness and stability.
一种有机电致发光元件,其霍尔传输层的结构是将空穴传输材料分散在
玻璃转化温度 Tg 不低于 170 ℃ 的粘结剂
树脂中。由于该有机电致发光元件的空穴传输层具有高耐久性和高空穴传输能力,因此该元件具有出色的发光效率、亮度和稳定性。
