Double-sided tape and display device including the same

A double-sided tape disposed between a curved display panel having a curvature in at least one direction and a curved mold frame having a shape corresponding to the display panel and configured to fix the display panel and the mold frame to each other, the double-sided tape comprising:

• a first adhesive layer comprising about 100 parts by weight of an acrylic polymer, about 1 to about 2 parts by weight of a silane coupling agent, and about 0.1 to about 0.18 parts by weight of carbon black, the first adhesive layer having a degree of crosslinking of about 40% to about 49% by weight and an optical density of about 5 or greater;
• a foamed polymer layer disposed on the first adhesive layer, the foamed polymer layer comprising a urethane foam, the foamed polymer layer having an optical density of about 5 or greater and a thickness of about 0.3 millimeters to about 1.15 millimeters;
• an interlayer polymer layer disposed on the foamed polymer layer, the interlayer polymer layer comprising a polyolefin, a polyethylene terephthalate, a polyester, or a combination thereof, the foamed polymer layer having an optical density of about 5 or greater and a thickness of about 0.045 millimeters to about 0.055 millimeters;
• and
• a second adhesive layer disposed on the interlayer polymer layer, the second adhesive layer comprising about 100 parts by weight of an acrylic polymer, about 1 to about 2 parts by weight of a silane coupling agent, and about 0.1 to about 0.18 parts by weight of carbon black, the second adhesive layer having a degree of crosslinking of about 40% to about 49% by weight and an optical density of about 5 or greater,
• wherein an overall thickness of the double-sided tape is in a range of about 0.4 millimeters to about 1.3 millimeters.
