Abstract

The invention discloses an OLED (Organic Light Emitting Diode) display panel which comprises a TFT (Thin Film Transistor) array substrate and a plurality of anodes arranged on the TFT array substrate in an array manner, wherein a pixel definition layer is arranged on the TFT array substrate in a coating manner, and comprises opening parts exposed out of the anodes and spacing parts used for spacing every two adjacent anodes; grooves are formed in the spacing parts; openings are formed at the upper parts of the grooves; each opening part corresponds to a sub-pixel region; a first common layer, a second common layer and a cathode layer are sequentially arranged on the pixel definition layer; an emissive unit is arranged corresponding to each sub-pixel region between the first common layer and the second common layer; and the first common layer, the second common layer and the cathode layer are provided with gaps corresponding to the grooves. The invention further discloses a preparation method of the OLED display panel and a display device comprising the OLED display panel.

Description

technical field [0001] The present invention relates to the technical field of displays, in particular to an OLED display panel and a preparation method thereof, and also to a display device including the OLED display panel. Background technique [0002] OLED (Organic Electroluminescent Diode) display devices have the characteristics of self-luminescence, wide viewing angle, high luminous efficiency, low power consumption, fast response time, good low temperature characteristics, simple manufacturing process, and low cost. Flexible OLED display devices have a profound impact on the application of wearable devices due to their advantages of light weight, bendability, and portability. In the future, flexible OLED display devices will be more widely used with the continuous penetration of personal smart terminals . [0003] The core component of an OLED display device is an OLED display panel. The structure of an OLED display panel generally includes: a TFT array substrate and...
