2 . The method of claim 1 , further comprising bending the display panel in a first direction,
wherein the first region, the second region, and the third region are arranged in the first direction.

3 . The method of claim 2 , further comprising forming one or more holes in the second region,
wherein the second region on which the holes are formed is cut to divide the printed circuit board into the first printed circuit unit and the second printed circuit unit.

4 . The method of claim 1 , wherein the connection member is provided on the printed circuit board to cover at least part of the opening.

5 . The method of claim 4 , wherein the connection member comprises a first coupling part, a second coupling part, and a connection part connecting the first coupling part to the second coupling part, and
the providing of the connection member comprises: bending a boundary between the first coupling part and the connection part; bending a boundary between the second coupling part and the connection part; electrically connecting the first coupling part to the first printed circuit unit; and electrically connecting the second coupling part to the second printed circuit unit.

6 . The method of claim 1 , wherein the connection member comprises a first coupling part, a second coupling part, and a connection part connecting the first coupling part to the second coupling part without covering the opening, and
the providing of the connection member comprises: electrically connecting the first coupling part to the first printed circuit unit; and electrically connecting the second coupling part to the second printed circuit unit.

7 . The method of claim 6 , wherein one side of the connection part has a bent portion in plan view, the one side of the connection part facing the opening.

8 . The method of claim 1 , wherein after the tape carrier package is attached to the display panel, the printed circuit board is divided into the first printed circuit unit and the second printed circuit unit, and after the printed circuit board is divided into the first printed circuit unit and the second printed circuit unit, the display panel is curved in a first direction.

9 . A printed circuit board unit comprising:
a first printed circuit unit; a second printed circuit unit electrically connected to the first printed circuit unit; an opening defined between the first printed circuit unit and the second printed circuit unit; and a connection member coupled to each of the first printed circuit unit and the second printed circuit unit to electrically connect the first printed circuit unit and the second printed circuit unit.

10 . The printed circuit board unit of claim 9 , further comprising one or more holes defined between the first printed circuit unit and the second printed circuit unit.
