The invention provides a packaging structure, and relates to the technical field of display screen assembly. The packaging structure comprises a display assembly, a backboard, a middle frame and a packaging layer, wherein the backboard comprises a first laminate, a second laminate and a third laminate; a first clearance is formed between the edge, which exceeds the second laminate, of the third laminate and the edge, which exceeds the second laminate, of the first laminate, a second clearance is formed between the third laminate and the middle frame, the packaging layer comprises a first portion, a bending portion and a second portion which are sequentially connected, the first portion is packaged in the first clearance, the second portion is packaged in the second clearance, and the bending portion wraps the edge of the third laminate; and the first laminate is bent towards the packaging layer and adheres to the outer side of the bending portion of the packaging layer. In the invention, the packaging layer can realize packaging at the edge of the backboard with a multi-layer structure, and the end part, which is bent towards the packaging layer, of the first laminate can press against the middle frame, thereby being capable of preventing a dispergation solution from entering between the backboard and the middle frame, and avoiding the packaging structure from being disassembled by the dispergation solution to result in damages.
