The bending region is configured to bend along a bending axis which extends in a first direction. A plurality of pad terminals is disposed within the second region. A first width of the bending region, measured along the first direction, is narrower than a second width of the second region, measured along the first direction. ## Claims ### Claim 1 A display device comprising: a single, unitary substrate including a first region in which an image is displayed, a second region in which a plurality of pad terminals are disposed, and a bending region being configured to bend along a bending axis which extends in a first direction and disposed between the first region and the second region; and a plurality of pixels and a plurality of signal lines disposed in the first region; and wherein the plurality of pad terminals are electrically connected to the plurality of signal lines, wherein a first width of the bending region, at its widest point, in the first direction, is narrower than a second width of the second region in the first direction, and wherein the bending region is bent such that the second region overlaps the first region. ### Claim 2 (depends on 1) The display device of claim 1, wherein the first region has a rounded edge in a portion adjacent to the bending region. ### Claim 3 (depends on 1) The display device of claim 1, wherein the bending region is bent such that the substrate of the bending region faces itself. ### Claim 4 (depends on 1) The display device of claim 1, wherein the bending region is bent such that the first region and the second region are perpendicular to each other. ### Claim 5 (depends on 1) The display device of claim 1, wherein the first width of the bending region is substantially identical over the entirety of the bending region. ### Claim 6 (depends on 1) The display device of claim 1, wherein the first width of the bending region is larger at an area closer to the second region than at an area closer to the first region. ### Claim 7 (depends on 1) The display device of claim 1, wherein the first width of the bending region is smaller at an area closer to the second region than at an area closer to the first region. ### Claim 8 (depends on 1) The display device of claim 1, wherein the first width of the bending region is smaller at a central area between the first region and the second region than at both an area that is closer to the first region and at an area that is closer to the second region. ### Claim 9 (depends on 1) The display device of claim 1, wherein the first width increases and then decreases from the first region toward the second region. ### Claim 10 (depends on 1) The display device of claim 1, wherein the first region has a substantially circular shape. ### Claim 11 (depends on 1) The display device of claim 1, wherein the first region has a substantially oval shape. ### Claim 12 (depends on 1) The display device of claim 1, further comprising: a plurality of connection wires disposed within the bending region and connecting the plurality of signal lines to the plurality of pad terminals. ### Claim 13 (depends on 12) The display device of claim 12, wherein: the plurality of connection wires includes a first connection wire and a second connection wire adjacent to the first connection wire, and the first connection wire and the second connection wire are disposed within a same layer. ### Claim 14 (depends on 12) The display device of claim 12, wherein the plurality of connection wires is disposed within a plurality of layers. ### Claim 15 (depends on 1) The display device of claim 1, wherein the plurality of signal lines transmits a scan signal or a data signal. ### Claim 16 (depends on 1) The display device of claim 1, further comprising a flexible circuit board bonded with the plurality of pad terminals and disposed within a first driving chip on one surface. ### Claim 17 (depends on 1) The display device of claim 1, further comprising a second driving chip disposed within the second region and electrically connected to the plurality of pad terminals. ### Claim 18 (depends on 1) The display device of claim 1, wherein a plurality of organic light emitting elements are disposed within the first region. ### Claim 19 (depends on 1) The display device of claim 1, wherein the second region has a substantially quadrangular shape. ### Claim 20 (depends on 1) The display device of claim 1, wherein the first region has a substantially quadrangular shape. ### Claim 21 (depends on 1) The display device of claim 1, wherein an image is displayed in the first region.
