Abstract: This disclosure relates to the field of display technologies, and in particular to an adhesive assembly, a flexible module, a display device and a manufacturing method of a flexible module. The adhesive assembly includes an adhesive base layer, which is arranged between two modules. The adhesive base layer includes a bonding region and a bending load buffer region, the bonding region being used for bonding the two modules, and a bending stress in the bending load buffer region being smaller than that in the bonding region. When two modules are bonded by such an adhesive assembly, the bending stress in the bending load buffer region and corresponding module portion is smaller than that in the bonding region and corresponding module portion for the whole flexible module, which reduces bending stress in the modules as a whole and facilitates spread and application of the flexible module.
