Abstract: A foldable display device includes a display panel, a polarizing member on the display panel, a window on the polarizing member, a first adhesive member between the display panel and the polarizing member, and a second adhesive member between the polarizing member and the window. In a first state, the display panel, the polarizing member, the window, the first adhesive member, and the second adhesive member are bent along a bending axis such that the window is closer to the bending axis than the display panel is. The first and second adhesive members have a storage modulus in a range of about 5×104 Pa to about 5×105 Pa at about −25° C. The second adhesive member has a storage modulus in a range of about 4.5×104 Pa to about 6.5×104 Pa at about 60° C. The first adhesive member has a stress-relaxation ratio greater than about 40 and less than about 50.
