Abstract: Disclosed belongs to the technical field of displaying, and particularly relates to a sealant tape, a display panel and methods for manufacturing the same. The sealant tape comprises a substrate and an adhesive layer provided on at least one side of the substrate, wherein the substrate comprises a first elastomer, and the adhesive layer comprises a second elastomer and a crosslinking agent. Both of the substrate and the adhesive layer of the sealant tape are formed of elastomeric materials, and the adhesive layer further comprises a crosslinking agent to adjust the storage modulus thereof, such that the sealant tape can withstand a higher stress while provides excellent bending performance, and has a higher viscosity to ensure that it will not be unglued when the display panel is folded and thus it can be prevented from being damaged during folding or bending of the flexible display panel, ensuring good packaging performance.
