Adhesive member, method of manufacturing display device including forming the adhesive member, and display device manufactured thereby

Abstract

An adhesive member of may include a polymer derived from a resin composition including at least one urethane (meth)acrylate oligomer including two (meth)acryloyl groups per oligomer unit, at least one polyfunctional (meth)acrylate monomer including multiple (meth)acryloyl groups per monomer unit, and at least one photoinitiator. The weight of the urethane (meth)acrylate oligomer may be 1 wt % or more and less than 10 wt %, and the weight of the polyfunctional (meth)acrylate monomer may be 0.2 wt % or more and less than 2 wt %, based on a total weight of the resin composition. The glass transition temperature of the adhesive member may be −10° C. or more and less than 10° C., and the loss tangent (tan δ) of the adhesive member at −40° C. may be 0.01 or more and less than 0.3. Accordingly, the adhesive member may undergo easy rework at −40° C. and show excellent or suitable adhesion reliability during use.
