In some cases, the first projecting piece and the second projecting piece overlap each other. In the configurations of Patent Document 3 and Patent Document 4, when the boxes are stacked, the two projecting pieces overlap each other. Since the fitting strength with the upper box is improved, the two protruding pieces may be misaligned and the two protruding pieces are displaced and overlapped. In such a case, there is a possibility that the hole cannot be easily fitted. For example, when two protruding pieces are displaced in the lateral direction and overlapped with each other, it may be difficult to fit into the hole. Further, since the overlapping projecting pieces are not bonded, the strength as the projecting pieces is not sufficient. That is, if the overlapping protruding pieces are not bonded, one protruding piece may be bent to the opposite side of the other protruding piece, and the strength is not sufficient.

  However, in the display device 5 of the present embodiment, the strength of the engaging portions 81 to 84 can be sufficiently obtained, and the two projecting pieces are not displaced in the lateral direction, and the holes of the engaging portions are moved. There is no hindrance to the engagement.
