The support plate includes a first support plate bonded to the adhesion film on the first non-folding area, and a second support plate bonded to the adhesion film on the second non-folding area. The first support plate includes a plurality of first protrusions protruding toward the second support plate, the second support plate includes a plurality of second protrusions protruding toward the first support plate, and the first and second protrusions are alternately arranged with respect to each other.
