Abstract

The invention provides a flexible base plate and a manufacturing method thereof, an array base plate, a display panel and a display device. The flexible base plate comprises at least one pattern layerand at least one blocking layer which are arranged on a substrate, and the at least one pattern layer comprises a first pattern layer arranged on the substrate and a second pattern layer in which atleast a part of patterns are positioned on the first pattern layer; the substrate, the first pattern layer and the second pattern layer are covered with the blocking layer, wherein one of the patternlayer and the blocking layer with which the pattern layer is covered is an inorganic film, and the other of the pattern layer and the blocking layer with which the pattern layer is covered is an organic film. The flexible base plate provided by the invention solves the technical problem that the organic film and the inorganic film in an existing flexible display screen are easy to separate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible substrate and a manufacturing method thereof, an array substrate, a display panel and a display device. Background technique [0002] Flexible display screens have been widely used in many fields such as portable electronic devices (such as mobile communication terminals, tablet computers, e-books and navigation equipment) and large-screen electronic devices due to their characteristics of being bendable or foldable. Organic Light-Emitting Diode (OLED for short) has been gradually applied to flexible display screens due to its low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility. [0003] At present, a flexible display using OLED usually includes: a flexible substrate and a thin film transistor layer arranged on the flexible substrate, several light-emitting units and a thin film encapsulation layer, wherein the fle...
