Optically clear resin composition and display device including the same
An optically transparent adhesive resin composition includes an ester polymer which contains an ester bond within a repeating unit, a (meth)acrylic ester polymer which contains a (meth)acrylic ester bond within the repeating unit, a rubber polymer, and a crystalline polymer.
1. A display device, comprising:
a cover window comprising a transparent area and an opaque area disposed outside the transparent area;
a display panel comprising a display area and a peripheral area disposed outside the display area;
a polarizing plate interposed between the display panel and the cover window; and
an optically transparent adhesive resin film comprising a crystalline polymer and a rubber polymer, the optically transparent adhesive resin film being configured to cover the polarizing plate and the display panel, and the optically transparent adhesive resin film has a shear strength greater than or equal to 65 N/cm 2 at 85° C.,
wherein:
the crystalline polymer comprises polycaprolactone or polycarbonate-diol;
the rubber polymer comprises at least one of polybutadiene, polyisoprene, polyneoprene, polyisobutylene, cellulose acetate, or polyvinyl acetate; and
a weight ratio of the rubber polymer and the crystalline polymer is in the range of 1:0.5 to 1:1.2.
2. The display device of claim 1 , wherein the optically transparent adhesive resin film has a glass transition temperature (Tg) in the range of 4° C. to 10° C.
3. The display device of claim 2 , wherein the optically transparent adhesive resin film has a shear strength greater than or equal to 300 N/cm 2 at 25° C.
