Display device

A display device comprising:

• a display panel;
• a window disposed on the display panel;
• a window protection layer disposed on the window;
• and
• a first adhesive layer disposed between the window and the window protection layer;
• wherein the first adhesive layer has a creep value of about 38.1876% to about 40.4371% at a temperature of about 25° C. when a stress of about 2,000 Pa is applied to the first adhesive layer for about 10 minutes,
• the first adhesive layer has a storage modulus of about 0.0317 MPa to about 0.0348 MPa and a loss modulus of about 0.0108 MPa to about 0.0120 MPa at the temperature of about 25° C. when a frequency of about 1 Hz and an axial force of about 1.0 N are applied and the first adhesive layer maintains a strain of about 1%;
• and wherein the first adhesive layer has a tan delta value of about 1.0216 to about 1.0519 at a temperature of about −20° C.,
• wherein the first adhesive layer comprises a silicon-based resin, an acrylic-based resin, or an urethane-based resin.

• the first adhesive layer has a tan delta value of about 0.3354 to about 0.3480 at the temperature of about 25° C. when a frequency of about 1 Hz and an axial force of about 1.0 N are applied and the first adhesive layer maintains a strain of about 1%,
• the tan delta value is defined by dividing a loss modulus by a storage modulus;
• and wherein the first adhesive layer has a tan delta value of about 1.0216 to about 1.0519 at a temperature of about −20° C.,
• wherein the first adhesive layer comprises a silicon-based resin, an acrylic-based resin, or an urethane-based resin.
