Abstract

The present disclosure relates to a flexible panel and the manufacturing method thereof. The method includes: coating photosensitive adhesive on a substrate to form a photosensitive layer; forming a scattering layer and an ultraviolet (UV) blocking layer on the photosensitive layer in sequence; forming a flexible substrate layer on the UV blocking layer; forming electronic components, lighting components, and an encapsulation layer on the flexible substrate layer in sequence; and irradiating the photosensitive layer from one side of the substrate by UV rays such that a peeling strength of the photosensitive layer being reduced, and the scattering layer being separated from the substrate to form the flexible panel. By configuring the photosensitive layer, the scattering layer, and the UV blocking layer on the substrate, the scattering layer may be easily separated from the substrate.
