    • A method of manufacturing an organic EL display unit and an organic EL display unit capable of improving light emitting efficiency and life of blue are provided. A hole injection layer are formed on a lower electrode. For a red organic EL device and a green organic EL device, a hole transport layer, a red light emitting layer, and a green light emitting layer made of a polymer material are formed. A hole transport layer made of a low molecular material is formed on the hole injection layer of a blue organic EL device. A blue light emitting layer made of a low molecular material is formed on the red light emitting layer, the green light emitting layer, and the hole transport layer for the blue organic EL device. An electron transport layer, an electron injection layer, and an upper electrode are sequentially formed on the blue light emitting layer.
    • 提供一种制造能够提高发光效率和蓝色寿命的有机EL显示单元和有机EL显示单元的方法。 在下电极上形成空穴注入层。 对于红色有机EL器件和绿色有机EL器件,形成空穴传输层,红色发光层和由聚合物材料制成的绿色发光层。 在蓝色有机EL器件的空穴注入层上形成由低分子材料制成的空穴传输层。 在蓝色有机EL器件的红色发光层,绿色发光层和空穴传输层上形成由低分子材料制成的蓝色发光层。 在蓝色发光层上依次形成电子传输层,电子注入层和上部电极。
