    Abstract: A foldable display is disclosed. In one aspect, the foldable display includes a foldable display panel and a folding adjustment part configured to adjust a folding configuration of the foldable display panel. The foldable display also includes a folding sensor configured to sense the folding configuration, a rear surface touch sensor configured to sense a touch input applied to a rear surface of the foldable display panel, and a controller. The controller is configured to detect first and second touch inputs applied to different portions of the rear surface and control the folding adjustment part so as to switch the folding configuration of the foldable display panel when the controller detects that the first touch input moves in a first direction and the second touch input moves in a second direction different from the first direction.

    Abstract: A display device includes: 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, a loss modulus of about 0.0108 MPa to about 0.0120 MPa, and 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%, and the tan delta value is defined by dividing the loss modulus by the storage modulus.
