Abstract
A flexible display device of the present invention comprises a photoelectric element part; a first adhesive film formed on the photoelectric element part; a touch function part formed on the first adhesive film; a second adhesive film formed on the touch function part; and a window film formed on the second adhesive film; wherein the first adhesive film or the second adhesive film has an average slope of about −9.9 to about 0 at −20° C. to 80° C. based on x-axis for the distribution of storage modulus versus temperature in the function of x-axis of temperature (° C.) and y-axis of storage modulus (KPa) and wherein the first adhesive film or the second adhesive film has a storage modulus of about 10 KPa or more at 80° C.
