Abstract: A method of manufacturing an adhesive member includes providing, for a substrate, a resin composition having a viscosity of about 5 cP to about 50 cP, as measured according to JISK2283 method, at about 25° C. The resin composition is exposed to a first light to form a preliminary adhesive member having a curing rate of about 80% to about 98%. The preliminary adhesive member is exposed to a second light having a light integral/dose that is more than that of the first light to form an adhesive member. The preliminary adhesive member may have a loss tangent (tan δ) of about 0.2 to about 0.6 and may have a glass transition temperature of about −70° C. to −30° C. Accordingly, the preliminary adhesive member and adhesive member formed by the method of manufacturing an adhesive member may exhibit increased reliability.
