The supporting part includes a plurality of springs that are arranged in a second direction and extend in a third direction, and are interwoven with each other. The first direction, second direction, and third direction are substantially orthogonal to each other. ## Claims ### Claim 1 A display device including a deformable display unit, the display device comprising: a display panel configured to display images in a first direction; and a supporting part positioned under the display panel, wherein the supporting part includes a plurality of springs that are arranged in a second direction and extend in a third direction, wherein each spring of the plurality of springs has a coil shape, wherein each spring of the plurality of springs is wrapped around an adjacent spring of the plurality of springs, and wherein the first direction, the second direction, and the third direction are substantially orthogonal to each other. ### Claim 2 (depends on 1) The display device of claim 1, wherein: the coil shape of each of the plurality of springs is spirally wrapped around an imaginary column extending in the third direction. ### Claim 3 (depends on 1) The display device of claim 1, wherein: the display unit is configured to be rolled or unfolded in the second direction. ### Claim 4 (depends on 3) The display device of claim 3, wherein: a coil pitch of each of the plurality of springs is equal to or greater than twice a diameter of the coil wiring. ### Claim 5 (depends on 1) The display device of claim 1, wherein: a first surface of the plurality of springs is flatter than a second surface opposite the first surface, wherein the first surface is adjacent to the display panel. ### Claim 6 (depends on 5) The display device of claim 5, further comprising: a first adhesive layer positioned between the first surface of the plurality of springs and the display panel. ### Claim 7 (depends on 1) The display device of claim 1, wherein: as a ratio of a mean coil diameter to a diameter of the coil wiring of the plurality of springs increases, a curvature radius corresponding to when the display unit is fully rolled decreases. ### Claim 8 (depends on 1) The display device of claim 1, wherein: when the display unit is fully rolled, outer surfaces of the springs that are alternately adjacent in the plurality of springs are in contact with each other. ### Claim 9 (depends on 8) The display device of claim 8, wherein: when the display unit is fully extended, inner surfaces of adjacent springs in the plurality of springs are in contact with each other. ### Claim 10 (depends on 1) The display device of claim 1, wherein: when the display unit is fully rolled, inner surfaces of adjacent springs in the plurality of springs are in contact with each other. ### Claim 11 (depends on 10) The display device of claim 10, wherein: when the display unit is fully extended, outer surfaces of the springs that are alternately adjacent in the plurality of springs are in contact with each other. ### Claim 12 (depends on 1) The display device of claim 1, wherein: the plurality of springs includes at least two springs of different sizes. ### Claim 13 (depends on 1) The display device of claim 1, wherein: a spiral shape of at least a part of the plurality of springs a circle or a polygon. ### Claim 14 (depends on 1) The display device of claim 1, wherein: the supporting pan further includes a resin layer in which the plurality of springs is disposed. ### Claim 15 A display unit capable of being rolled or unfolded in a first direction, comprising: a display panel; a lower film part positioned under the display panel; and a supporting part positioned under the lower film part, wherein the supporting part includes a plurality of springs arranged in the first directions, wherein each spring of the plurality of springs has a coil shape and wherein each spring of the plurality of springs is wrapped around an adjacent spring of the plurality of springs. ### Claim 16 (depends on 15) The display device of claim 15, wherein: the coil shape of each of the plurality of springs is spirally wrapped around an imaginary column extending in a second direction, wherein the second direction is different from the first direction. ### Claim 17 (depends on 15) The display device of claim 15, wherein: a coil pitch of each of the plurality of springs is equal to or greater than twice a diameter of the coil wiring. ### Claim 18 (depends on 15) The display device of claim 15, wherein: a first surface of the plurality of springs is flatter than a second surface opposite the first surface, wherein the first surface is adjacent to the display panel. ### Claim 19 (depends on 18) The display device of claim 18, further comprising: an adhesive layer positioned between the first surface of the plurality of springs and the lower film part. ### Claim 20 A display device comprising: a display unit capable of being rolled or unfolded in a first direction, wherein the display unit includes: a display panel that can display images; and a supporting part positioned under the display panel, and wherein the supporting part includes a plurality of springs arranged in the first direction, and wherein each of the plurality of springs extends in a form of a coil in a second direction different from the first direction, and wherein each spring of the plurality of springs is wrapped around an adjacent spring of the plurality of springs.
