Abstract

The invention provides a flexible display device and a manufacturing method thereof. The flexible display device comprises a flexible substrate, at least two polyimide layers and at least one inorganic film, wherein the at least two polyimide layers are formed on one side of the flexible substrate; the at least one inorganic film is formed between the two polyimide layers, a plurality of protrusions are arranged on one surface of the inorganic film, and gaps among the protrusions communicate with one another to form a plurality of bending stress passages parallel to one another in at least onedirection. According to the flexible display device and the manufacturing method thereof provided by the invention, the bending stress passages matched with the bending direction are arranged on theinorganic film between the first polyimide layer and the second polyimide layer, so that the internal stress between the two polyimide layers during bending in the single direction is relieved, the bending breakage probability when the inorganic film is bent at a relatively large angle is reduced, the internal stress of a flexible organic light-emitting device is improved, the reliability of the flexible organic light-emitting device is guaranteed, and simultaneously, the water blocking capacity of the inorganic film is guaranteed.

Description

Technical field [0001] The present invention relates to the field of OLED panel manufacturing process, in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] Nowadays, flexible electronics and flexible displays have become research hotspots in recent years; flexible display electronic products with fixed curved surfaces, bendable, foldable and even rollable, including flexible thin film transistor liquid crystal displays (Flexible TFT-LCD), flexible organic light emitting Displays (Flexible OLED) have gradually become the most promising high-tech industries. Many domestic and foreign mobile phone panel manufacturers have invested heavily in related research and verification, vying to seize the technology and commercial opportunities of flexible EL. [0003] figure 1 It is a cross-sectional view of an existing flexible organic light emitting device. Such as figure 1 As shown, the existing flexible organic light emitting device ...
