This application discloses an optical adhesive, its preparation method, an optical adhesive film, and a display device, belonging to the field of optical adhesive technology. By compounding a modified acrylate copolymer with a polyurethane acrylate oligomer in the raw materials of the optical adhesive, a highly transparent resin system can be formed. The modified acrylate copolymer is a copolymer pre-formed from at least one acrylate derivative. Compared to ordinary acrylate monomers, the modified acrylate copolymer possesses high refractive index and low light scattering characteristics, effectively improving light transmittance. Furthermore, this highly transparent resin system achieves good light transmittance without relying on nanoparticles, avoiding the problem of nanoparticle agglomeration, thereby improving the haze of the optical adhesive layer obtained from the optical adhesive.
