Abstract: Provided are a backboard support structure, a preparation method therefor, and a display device. The display device includes a display substrate and a backboard support structure; the backboard support structure includes a substrate support film and an adhesive layer arranged in a laminated manner. The backboard support structure is bonded to the non-display side of the display substrate via the adhesive layer, and includes a first bendable region and a first non-bent region. The adhesive layer includes a first portion located in the first bendable region and a second portion located in the first non-bent region; the first portion has a modulus of elasticity of about 1 Kpa-150 Kpa, the second portion has a modulus of elasticity of about 150 Kpa-250 Kpa, and the substrate support film has a modulus of elasticity of about 1 Gpa-10 Gpa.

Abstract: A display panel. The display panel includes a base substrate; a plurality of light emitting elements on the base substrate; and an encapsulating structure encapsulating the plurality of light emitting elements. The encapsulating structure includes a first inorganic encapsulating sublayer; a first organic encapsulating sublayer; and a first amphiphilic cross-linking sublayer between the first inorganic encapsulating sublayer and the first organic encapsulating sublayer.
