Abstract

The invention discloses an organic electroluminescent display device and a manufacturing method and a display device of the organic electroluminescent display device. A multifunctional composite film layer is adopted for a substrate bearing an organic electroluminescent pixel array. The substrate comprises a body material film layer, a first phase difference film layer, a water blocking oxygen film layer and a polarized light function film layer, wherein the body material film layer, the first phase difference film layer, the water blocking oxygen film layer and the polarized light function film layer are arranged in a mutual stacking mode, the first phase difference film layer and the polarized light function film layer have the anti-reflection effect after being combined, and the water blocking oxygen film layer has the water blocking oxygen performance. Thus, the substrate can have both the anti-reflection effect and the good water blocking oxygen performance, the secondary film pasting technology for pasting circular polarizers and the water blocking oxygen film layer on the bottom-emission type organic electroluminescent display device manufactured on the substrate can be omitted, the manufacturing process is simplified, production cost is reduced, and meanwhile the curving difficulty problem caused by the situation that the flexible device is thickened because of secondary film pasting can be avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescence display device, a preparation method thereof and a display device. Background technique [0002] At present, compared with traditional liquid crystal display devices (Liquid Crystal Display, LCD), organic electroluminescent display devices (Organic Electroluminescent Display, OLED) have the characteristics of fast response, wide color gamut, ultra-thin, and flexibility. Has gradually become the mainstream of the display field. [0003] The structure of the OLED display device mainly includes: a base substrate, an organic electroluminescent pixel array fabricated on the substrate substrate; wherein, each organic electroluminescent pixel array includes an anode and a cathode arranged oppositely, and between the luminous layers. The light emission of the OLED display device is realized by exciting the organic material in the light-emitting layer to ...
