Abstract
A deformation-controlling film includes a protective layer and a deformation-controlling layer. The deformation-controlling layer is connected to the protective layer, and a surface of the deformation-controlling layer away from the protective layer has an adhering structure. The adhering structure includes a plurality of bumps. The plurality of bumps protrudes from the surface of the deformation-controlling layer in a direction away from the protective layer, and an air-leaving channel is formed between adjacent two of the plurality of bumps.
