Abstract

The embodiment of the invention discloses a supporting plate and a manufacturing method thereof and a flexible display device. The supporting plate comprises a hard substrate, an adhesive layer and a flexible layer. The hard substrate is provided with a groove structure, the adhesive layer is arranged on the hard substrate, the flexible layer is arranged on the side, away from the hard substrate, of the adhesive layer, the side, close to the hard substrate, of the flexible layer is provided with a protruding structure, and the protruding structure corresponds to the groove structure; and a part of the adhesive layer is located in the groove structure. According to the invention, the flatness of the flexible layer after being attached to the hard substrate can be ensured, and the side, far away from the hard substrate, of the flexible layer is prevented from being printed.

Description

Technical field [0001] The present application relates to the field of display technology, and more particularly to a support plate and a method of fabricating a method, a flexible display device. Background technique [0002] In recent years, the flexible display panel has received extensive attention due to unique bending and folding characteristics. As the flexible display panel is getting smaller and smaller, the flexible display panel is getting thinner and more tends to be thinner in order to facilitate bending or decrection operation. [0003] However, as the flexible display panel is thin, its mechanical properties and recovery properties will inevitably reduce. Thus, the prior art typically plans a support plate on the back surface of the flexible display panel to provide support for the flexible display panel. In order to ensure the bend resistance of the flexible display panel, a hollow pattern is typically provided in the support plate such that the flexible layer abo...
