The driving chip is configured to generate the driving signal, the driving circuit film is configured to apply the driving signal to the display panel, and the driving circuit film is coupled to the terminal part and bent toward a lower surface of the display panel. The display panel and a surface of the spacer are curved along a first direction. ## Claims ### Claim 1 A curved display device comprising: a display panel curved along a first direction, the display panel comprising a terminal part configured to receive a driving signal; a driving circuit film comprising a base film and a driving chip centered on the base film, the driving chip being configured to generate the driving signal, the driving circuit film being configured to apply the driving signal to the display panel, and the driving circuit film being coupled to the terminal part and bent toward a lower surface of the display panel; and a spacer disposed between the base film and the display panel, wherein a first surface of the spacer contacting a lower surface of the display panel is curved by the display panel along the first direction, a second surface of the spacer is nonparallel with the first surface in the first direction, and the second surface is opposite the first surface, and wherein a height of the first surface of the spacer from the base film is greater than a height of a surface of the driving chip facing the lower surface of the display panel from the base film. ### Claim 2 (depends on 1) The curved display device of claim 1, wherein a display area of the display panel and the lower surface of the display panel have a curved shape. ### Claim 3 (depends on 2) The curved display device of claim 2, wherein the spacer has a supporting surface contacting the lower surface of the display panel, and the supporting surface has a curved shape corresponding to the curved shape of the lower surface. ### Claim 4 (depends on 2) The curved display device of claim 2, wherein the spacer is between the lower surface of the display panel and the driving chip. ### Claim 5 (depends on 4) The curved display device of claim 4, wherein the spacer extends past both sides of the driving chip. ### Claim 6 (depends on 2) The curved display device of claim 2, wherein the spacer is between the lower surface of the display panel and the base film. ### Claim 7 (depends on 6) The curved display device of claim 6, wherein the spacer comprises two spacers, the spacers being spaced from and at opposite ends of the driving chip, respectively. ### Claim 8 (depends on 6) The curved display device of claim 6, wherein the spacer has a closed-loop shape to surround a perimeter of the driving chip. ### Claim 9 (depends on 6) The curved display device of claim 6, wherein the spacer surrounds a portion of a perimeter of the driving chip. ### Claim 10 (depends on 1) The curved display device of claim 1, wherein the terminal part extends along the first direction. ### Claim 11 (depends on 10) The curved display device of claim 10, wherein a shorter side of the display panel is curved along the first direction. ### Claim 12 (depends on 10) The curved display device of claim 10, wherein a longer side of the display panel is curved along the first direction. ### Claim 13 (depends on 10) The curved display device of claim 10, wherein the driving chip extends along the first direction. ### Claim 14 (depends on 1) The curved display device of claim 1, further comprising a driving circuit board adjacent to the lower surface of the display panel and electrically coupled to the driving circuit film, wherein the driving circuit film is bent from the terminal part toward the driving circuit board. ### Claim 15 (depends on 1) The curved display device of claim 1, further comprising: a window substrate comprising a light transmissive portion and covering the display panel; and a touch screen between the window substrate and the display panel and configured to detect a touch position generated on the window substrate, wherein the window substrate and the touch screen are curved together with the display panel. ### Claim 16 (depends on 1) The curved display device of claim 1, wherein the display panel comprises a display area having a curved shape, and the display area has a concave shape. ### Claim 17 (depends on 1) The curved display device of claim 1, wherein the display panel comprises a display area having a curved shape, and the display area has a convex shape. ### Claim 18 (depends on 6) The curved display device of claim 6, wherein the spacer has a closed-loop shape and overlaps a portion of the driving chip. ### Claim 19 (depends on 6) The curved display device of claim 6, wherein the spacer extends along at least a portion of a side of the driving chip and extends past the side and an opposite side of the driving chip. ### Claim 20 (depends on 1) The curved display device of claim 1, wherein the spacer comprises: a plurality of first portions extending in the first direction; and a plurality of second portions extending in a second direction crossing the first direction, and wherein a width of each of the first portions is different from a width of each of the second portions. ### Claim 21 (depends on 1) The curved display device of claim 1, wherein the driving chip is on a first surface of the base film, and wherein an angle between the display panel and the first surface of the base film is different than 0°. ### Claim 22 (depends on 1) The curved display device of claim 1, wherein the lower surface of the display panel has a convex shape, the first surface of the spacer has a concave shape, and the first surface of the spacer has the same curvature as the lower surface of the display panel.
