==ADHESIVE MEMBER, METHOD OF MANUFACTURING DISPLAY DEVICE INCLUDING FORMING THE ADHESIVE MEMBER, AND DISPLAY DEVICE MANUFACTURED THEREBY - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18471044 titled 'ADHESIVE MEMBER, METHOD OF MANUFACTURING DISPLAY DEVICE INCLUDING FORMING THE ADHESIVE MEMBER, AND DISPLAY DEVICE MANUFACTURED THEREBY

The adhesive member described in the patent application is made from a resin composition containing a urethane (meth)acrylate oligomer, a polyfunctional (meth)acrylate monomer, and a photoinitiator.

* The urethane (meth)acrylate oligomer in the adhesive member is present at a weight of 1 wt % or more and less than 10 wt %, while the polyfunctional (meth)acrylate monomer is present at a weight of 0.2 wt % or more and less than 2 wt %.
* The adhesive member has a glass transition temperature of -10°C or more and less than 10°C, and a loss tangent (tan δ) at -40°C of 0.01 or more and less than 0.3.
* The adhesive member allows for easy rework at -40°C and exhibits excellent adhesion reliability during use.

==Original Abstract Submitted==

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.
