1. A method of manufacturing an adhesive film for a display device, the method comprising:
forming, on a first release film, a first composition comprising a resin and a first initiator for initiating a polymerization reaction of the resin;
forming, on the first composition which has been applied, a second composition comprising the resin and a second initiator for initiating the polymerization reaction of the resin;
irradiating the first composition and the second composition, which have been applied, with light having a first range of wavelengths; and
irradiating the first composition and the second composition, which have been applied, with light having a second range of wavelengths,
wherein the first initiator initiates the polymerization reaction of the resin with the light having the first range of wavelengths without activating initiation of the polymerization reaction with the light having the second range of wavelengths, and
wherein the second initiator initiates the polymerization reaction of the resin with the light having the second range of wavelengths without activating the initiation of the polymerization reaction with the light having the first range of wavelengths.
