Abstract

The invention discloses an array substrate and a manufacturing method thereof, and a display device. The array substrate has a bending area and a pixel area adjacent to the bending area, the pixel area has a plurality of pixel unit areas and a non-pixel unit area connected with the pixel unit area; the array substrate includes: a flexible substrate and an array layer, wherein the array layer includes an array base layer having a first groove and a second groove, the first groove corresponds to the non-pixel unit area in the pixel area, and the second groove corresponds to the bending area; a filling layer filled in the first groove and the second groove; and an organic dielectric layer covering the array base layer and the filling layer, wherein the organic dielectric layer and the fillinglayer employ organic photoresist materials. The array substrate and the manufacturing method thereof, and the display device having the array substrate effectively reduce the stress of each film layer in the array substrate when the film layers are bent so as to achieve bending of the pixel area.

Description

technical field [0001] The present invention relates to the fields of display devices and the like, and specifically relates to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode) display has become the mainstream display trend due to its self-illumination, wide viewing angle, high contrast, fast response and other characteristics. At present, with people's pursuit of the ultimate display experience, full screens and narrow bezels have become development hotspots in the current display field. The flexible OLED display is even more popular and has become a trend. It has many advantages, such as ultra-thin and ultra-light screen, smaller size, more convenient to carry, and stronger customer experience. [0003] At present, there is no fully flexible display mobile phone on the market, and only partial bending is performed in the bending area. In the flexible OLED display in the prior art, ...
