Classification: CPC C | IPC C

Claim 7:
8. 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 includes a polymer derived from a resin composition having at least one (meth)acrylate monomer, at least one urethane (meth)acrylate oligomer, and at least one photoinitiator,
where the at least one (meth)acrylate monomer comprises 2-ethylhexyl-diglycol acrylate,
wherein the adhesive member has a glass transition temperature in a range of about −70° C. or to about −30° C., a 180° peel force of about 800 gf/25 mm or greater for a glass substrate at a temperature of 25° C., and a deformation recovery rate in a range of about 75% or greater to less than about 100% at temperatures of −20° C. and 60° C.,
wherein the deformation recovery rate satisfies the following equation:

X2=[1−(X1/25)]×100%,

wherein
X1 denotes a shear strain measured 600 seconds after removing a shear stress applied in a way such that the adhesive member has a shear strain of 25% at the temperatures of −20° C. and 60° C., and
X2 denotes the deformation recovery rate.
