[0126] Therefore, a component constituting the electronic device ED such as the display panel DP may be spaced apart from the housing HAU by a predetermined space in the second direction DR2. The predetermined space corresponds to a part of the first peripheral region F-NAA (see Figure 1A ).

[0197] According to an embodiment of the present invention, even if the fourth side wall portions S-R1 and S-R2 of the support plate SP are bent from the bottom portion S-B, since the (4-1) side wall portion S-R1 and the (4-2) side wall portion S-R2 are spaced apart from each other, the bending region BA (see Figure 5 ) of the display panel DP (see Figure 5 ) can be easily bent to be accommodated in the housing HAU (see Figure 3 ).
[0198] Since each of the corners S-M of the bottom portion S-B has a vertical shape as shown in Figure 8B , the corresponding side surfaces of adjacent side wall portions among the side wall portions S1-U, S1-B, S2-U, S2-B, S-L, S-R1, and S-R2 can contact each other when accommodated in the housing HAU (see Figure 3 ).

Therefore, the distance from the housing HAU (see Figure 3 ) to each of the side wall portions S1-U, S1-B, S2-U, S2-B, S-L, S-R1, and S-R2 can be reduced.
[0200] The support plate SP-b to be referred to in Figure 9A and Figure 9B will mainly be from the reference Figure 8A and Figure 8Bwill be described by the differences of the described support plate SP-a.

[0202] Different from the support plate SP-a described with reference to Figure 8A and Figure 8B , the support plate SP-b according to the present embodiment may not include the fourth side wall portions S-R1 and S-R2. Therefore, even when the width of the bending region BA (see Figure 5 ) of the display panel DP (see Figure 5 ) increases in the first direction DR1, the bending region BA (see Figure 5 ) of the display panel DP (see Figure 5 ) can also be easily bent to the lower portion of the support plate SP-b.

[0212] In the board SP-1 according to the present embodiment, a lower board SP2 having relatively high rigidity may be disposed below the support board SP1 to supplement the rigidity of the board SP-1. In addition, since the first board SP2-1 and the second board SP2-2 are spaced apart from each other and the folding area FA is therebetween, the folding operation of the electronic device ED-1 can be performed more easily.

Since each of the side wall portions S1-U, S1-B, S2-U, S2-B, S-L, S-R1, S-R2, and S-C includes the holes S-H, the side wall portions S1-U, S1-B, S2-U, S2-B, S-L, S-R1, S-R2, and S-C can be easily bent when housed in the housing HAU.
[0217] According to an embodiment, the electronic device ED-2 may further include a cover tape TP.

The protruding part S-P can be coupled to its corresponding hole S-H1 to stably fix the main body S-B to the support plate SP-3.
[0225] Refer to Figure 12C , the sub-coupling part SC-2 can include a main body S-B, a protruding part S-P, and an additional support part S-S. Each of the sub-coupling parts SC-2 can have a smaller width than the main coupling part SC-1 in the first direction DR1, and thus the coupling force between the sub-coupling part SC-2 and the support plate SP-3 can be weak. Therefore, an additional support part S-S that contacts the side surface S-E of the support plate SP-3 can also be included.
