a sealing member disposed between the first circuit board and the second circuit board to seal a space between the first connector and the second connector; and
a coupling member coupling the first circuit board and the second circuit board to each other,
wherein at least one of the first circuit board and the second circuit board is a flexible board, and
wherein the first circuit board or the second circuit board, which is the flexible board, further includes a reinforcing member provided on the other face of the second circuit board to support the flexible board,
wherein the reinforcing member is disposed opposite to the second connector with the second circuit board therebetween, and
wherein the coupling member comprises: at least one coupling protrusion provided on the first circuit board to protrude from one face to be spaced apart from the first connector by a predetermined interval; a coupling hole provided in the second circuit board, and penetrating the second circuit board to be connected to the at least one coupling protrusion; and a fastening member couple to the at least one coupling protrusion through the coupling hole.

2. The apparatus of claim 1 , wherein the second connector is connected to the first connector while enclosing an outside portion of the first connector, and
the sealing member is disposed around a periphery of the second connector.

3. The apparatus of claim 1 , wherein the first connector is connected to the second connector while enclosing an outside portion of the second connector, and
the sealing member is disposed around a periphery of the first connector.

4. The apparatus of claim 1 , wherein the sealing member includes protruding portions protruding toward the first circuit board and the second circuit board, to be coupled in closed contact with the first circuit board and the second circuit board.

5. The apparatus of claim 1 , wherein at least one of the first circuit board and the second circuit board includes a first connector body, and a remaining one of the first circuit board and the second circuit board includes a second connector body such that the first connector body is seated on the second connector body or the second connector body is seated on the first connector body.

6. The apparatus of claim 5 , wherein the first connector body includes the first connector and a coupling opening of the coupling member adjacent to the first connector, and the second connector body includes the second connector and a coupling hole of the coupling member adjacent to the second connector.

7. The apparatus of claim 5 , wherein the sealing member is disposed along a periphery of one of an outer peripheral face of the first connector body and an outer peripheral face of the second connector body.

8. The apparatus of claim 6 , wherein the coupling opening and another coupling opening are disposed in the first connector body at each of opposite sides of the first connector, and
the coupling hole and another coupling hole are disposed in the second connector body at each of opposite sides of the second connector.

9. The apparatus of claim 6 , wherein the first connector and a third connector are disposed on the first connector body at each of opposite sides of the coupling opening, and
the second connector and a fourth connector are disposed on the second connector body at each of opposite sides of the coupling hole.

10. The apparatus of claim 1 , wherein at least one of the first circuit board and the second circuit board includes a fixing member to fix the sealing member.

11. The apparatus of claim 10 , wherein the sealing member is between the fixing member and a remaining one of the first circuit board and the second circuit board.

12. The apparatus of claim 10 , wherein the fixing member is provided in a closed loop shape along a periphery of the first connector of the first circuit board and the second connector of the second circuit board, and
the sealing member is provided to be coupled to an upper peripheral face of the fixing member, and to protrude toward one of the first circuit board and the second circuit board.

13. The apparatus of claim 10 , wherein the fixing member is provided in a closed loop shape along a periphery of the first connector of the first circuit board and the second connector of the second circuit board, and
the sealing member is provided to be coupled to an inner peripheral face of the fixing member, and to protrude toward the first connector or the second connector.

14. The apparatus of claim 13 , wherein the sealing member includes an inclined sealing face formed in a protruding portion.

15. The apparatus of claim 13 , further comprising:
a pressing protrusion formed on an end of the sealing member to be pressed by the first circuit board or the second circuit board.

16. An apparatus comprising:
a first circuit board;
a first connector provided on one face of the first circuit board;
a second circuit board disposed on the one face of the first circuit board, and electrically connected to the first circuit board;
a second connector provided on one face of the second circuit board, and engaged with the first connector to electrically connect the second circuit board to the first circuit board;
a sealing member disposed between the first circuit board and the second circuit board to seal a space between the first connector and the second connector; and
a coupling member coupling the first circuit board and the second circuit board to each other,
wherein at least one of the first circuit board and the second circuit board is a flexible board,
wherein the first circuit board or the second circuit board, which is the flexible board, further includes a reinforcing member provided on the other face of the second circuit board to support the flexible board,
