Resin composition, adhesive member, and display device including the same

An adhesive member comprising:

• a polymer derived from a resin composition, the adhesive member having a glass transition temperature in a range of about −50° C. to about 0° C., wherein
• the resin composition includes:
• a (meth)acrylate (A) comprising a hydroxy group and having a molecular weight of about 500 or less;
• a polymer (B) comprising polyisoprene or polybutadiene as a main skeleton, having at least one radical reactive group in one molecule, and having a molecular weight in a range of about 2,000 to about 35,000;
• a monofunctional (meth)acrylate (C) different from the (meth)acrylate (A), and
• a urethane (meth)acrylate oligomer (D) having a molecular weight of about 6,000 or greater
• the resin composition has a viscosity in a range of about 5 mPa·s to about 50 mPa·s at a temperature in a range of about 20° C. to about 30° C., and
• the resin composition comprises, with respect to a total amount of the resin composition:
• the (meth)acrylate (A) in an amount in a range of about 5 wt % to about 30 wt %;
• the polymer (B) in an amount in a range of about 0.1 wt % to about 5 wt %;
• the monofunctional (meth)acrylate (C) in an amount in a range of about 50 wt % to about 88 wt %;
• and
• the urethane (meth)acrylate oligomer (D) in an amount in a range of about 1 wt % to about 15 wt %.

A display device comprising:

• a display panel;
• a window disposed on the display panel;
• and
• an adhesive member disposed between the display panel and the window, wherein
• the adhesive member has a glass transition temperature in a range of about −50° C. to about 0° C. and is derived from a resin composition,
• the resin composition includes:
• a (meth)acrylate (A) comprising a hydroxy group and having a molecular weight of about 500 or less;
• a polymer (B) comprising polyisoprene or polybutadiene as a main skeleton, having at least one radical reactive group in one molecule, and having a molecular weight in a range of about 2,000 to about 35,000;
• a monofunctional (meth)acrylate (C) different from the (meth)acrylate (A);
• and
• a urethane (meth)acrylate oligomer (D) having a molecular weight of about 6,000 or greater,
• the resin composition has a viscosity in a range of about 5 mPa·s to about 50 mPa·s at a temperature in a range of about 20° C. to about 30° C., and
• the resin composition comprises, with respect to a total amount of the resin composition:
• the (meth)acrylate (A) in an amount in a range of about 5 wt % to about 30 wt %;
• the polymer (B) in an amount in a range of about 0.1 wt % to about 5 wt %
• the monofunctional (meth)acrylate (C) in an amount in a range of about 50 wt % to about 88 wt %;
