2 . The display device according to claim 1 ,
wherein a length of the first terminal portion in a direction of arranging a plurality of terminals is near or equal to a length of the first edge.

3 . The display device according to claim 2 , further comprising a third edge bent annularly,
wherein a distance between an endmost terminal in the first terminal portion and the third edge proximate to the endmost terminal is less than or equal to a distance between the endmost terminal and a terminal adjacent to the endmost terminal.

4 . The display device according to claim 3 , further comprising a third edge bent annularly,
wherein at least one terminal sequentially arranged from the endmost terminal is a dummy terminal.

5 . The display device according to claim 1 , further comprising a third edge bent annularly,
wherein a distance between an endmost terminal in the first terminal portion and the third edge proximate to the endmost terminal is greater than a distance between the endmost terminal and a terminal adjacent to the endmost terminal, and a dummy electrode is disposed between the endmost terminal and the third edge.

6 . The display device according to claim 1 ,
wherein the first surface of the electronic circuit board and the first terminal portion are connected via an anisotropic conductor, and the second surface of the electronic circuit board and the second terminal portion are connected via an anisotropic conductor.

7 . The display device according to claim 1 ,
wherein a touch sensor layer is disposed on the back face.

8 . The display device according to claim 1 , further comprising:
a TFT layer including the first terminal portion; a light-emitting element layer disposed in a layer above the TFT layer; a barrier layer disposed in a layer under the TFT layer; and a resin layer disposed in a layer under the barrier layer.

9 . The display device according to claim 8 ,
wherein the TFT layer and the second terminal portion are electrically connected via a contact hole extending through the TFT layer and the barrier layer, and an opening is disposed in the resin layer such that the opening overlaps the second terminal portion and the second terminal is exposed in the back face of the end portion on the second edge.

10 . The display device according to claim 1 ,
wherein a light-emitting face is applied to an inner face of a transmissive cylindrical covering.

11 . A display device with a first edge and a second edge, the first edge and the second edge extending in a same direction, the display device comprising:
