1. A method of manufacturing an adhesive member, comprising:
providing, on a substrate, a resin composition having a viscosity of about 5 cP to about 50 cP (exclusive of 50), as measured according to a JISK2283 method, at about 25° C.;
exposing the resin composition to a first light to form a preliminary adhesive member having a curing rate of about 80% to about 98% (exclusive of 80 and 98); and
exposing the preliminary adhesive member to a second light having a light integral that is greater than a light integral of the first light to form an adhesive member,
wherein the preliminary adhesive member has a loss tangent (tan δ) of about 0.2 to about 0.6 (exclusive of 0.6), and the adhesive member has a glass transition temperature of about −70° C. to about −30° C. (exclusive of −30).
