Abstract

The invention provides an organic light-emitting diode (OLED) luminescent device and an OLED display device. The OLED luminescent device comprises a cathode, a luminescent layer, an anode, a substrate and a light extraction layer. The light extraction layer at least comprises a first material layer and a second material layer. The first material layer is positioned on the substrate, and the second material layer is positioned on the first material layer. The first material layer and the second material layer have a first contact surface and a second contact surface which are contacted to each other respectively. Vertical sections of the first contact surface and the second contact surface are in a mutually-nested regular zigzag form. The refractive index of the first material layer n[A], the refractive index of the substrate n[substrate] and the refractive index of the second material layer n[B] meets the relation of n[A]>n[substrate]>n[B]. The substrate is provided with the first material layer and the second material layer which are provided with the first contact surface and the second contact surface respectively, the vertical sections of the first contact surface and the second contact surface are in a mutually-nested regular zigzag form, and the relation of n[A]>n[substrate]>n[B] is defined, so that emission of light from the side surface of the OLED luminescent device is reduced, the light emission amount of the luminescent surface of the OLED luminescent device is increased, and the light out-coupling efficiency of the OLED luminescent device is improved.

Description

【Technical field】 [0001] The invention relates to the field of display manufacturing, in particular to an OLED light-emitting device and a display device. 【Background technique】 [0002] At present, because OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) has many advantages such as self-illumination, wide viewing angle, fast response speed, high contrast, low energy consumption, green environmental protection, long life, ultra-thin and flexible display, it is widely recognized. Focus for next generation display technology. [0003] like figure 1 As shown, a typical OLED light-emitting device is composed of a glass substrate 10, an ITO (indium tin oxide, indium tin oxide) anode (Anode) 20, an organic light-emitting layer 30 (EmittingMaterialLayer) and a cathode 40 (Cathode), wherein the ITO anode 20 The organic light-emitting layer 30 is sandwiched between the metal cathode 40 and the organic light-emitting layer 30. When the holes (Hole) injected into the...
