wherein the plate part comprises a first surface facing the bendable member and a second surface facing a direction opposite to the first surface, and
wherein at least a portion of the bendable member is bent while being in close contact with the first surface of the plate part through the plurality of engaging protrusions.
4. The electronic device of claim 3 , further comprising a friction reducing structure disposed between the second surface and the plurality of engaging protrusions.
5. The electronic device of claim 4 , wherein the friction reducing structure comprises a Teflon coating layer or a hard coating layer disposed on a contact portion of at least one of the second surface or the plurality of engaging protrusions.
6. The electronic device of claim 3 ,
wherein the pressing part comprises a distancing space by which the pressing part is at least partially divided into a first portion and a second portion, and
wherein the distancing space is connected to the guide slit.
7. The electronic device of claim 6 , wherein the first portion and the second portion are connected to each other through a connection part having a diameter smaller than that of the pressing part.
8. The electronic device of claim 7 , wherein the connection part is integrally formed with the pressing part.
9. The electronic device of claim 7 , wherein the connection part connects the second portion to the first portion to be fixed to the support plate.
10. The electronic device of claim 3 , further comprising:
an auxiliary plate portion extending from the pressing part to correspond to at least a portion of the second surface and spaced apart from the plate part by a predetermined interval,
wherein when the first surface is viewed from above, the auxiliary plate portion comprises at least one auxiliary guide slit formed to overlap the guide slit.
11. The electronic device of claim 1 , wherein the plurality of engaging protrusions are disposed in a corresponding section of the bendable member, corresponding to a section where the flexible display is bent during transition from the slide-in state to the slide-out state.
12. The electronic device of claim 1 , wherein the flexible display is attached to the bendable member to be fixed thereto.
13. The electronic device of claim 1 ,
wherein the plurality of multi-bars are coupled to be rotatable with respect to each other, and
wherein the plurality of engaging protrusions are integrally formed with the plurality of multi-bars.
14. The electronic device of claim 1 , further comprising:
a guide rail disposed in the first housing or the second housing among the first housing and the second housing,
wherein the remaining housing is coupled to be guided in the first direction along the guide rail.
15. The electronic device of claim 1 , wherein the guide slit is disposed within a range corresponding to 50% of an entire length, with reference to a center of the each of the plurality of multi-bars, along a second direction perpendicular to the first direction.
16. The electronic device of claim 1 , further comprising
at least one guide roller rotatably coupled to each of the plurality of engaging protrusions,
wherein the at least one guide roller is in contact with the support plate.
17. The electronic device of claim 1 , wherein the plurality of engaging protrusions are disposed to penetrate the support plate through the guide slit and then to be engaged with a rear surface of the support plate.
18. A display device comprising:
a flexible display comprising a bent region that is at least partially bent according to deformation of at least one housing;
a bendable member disposed to support at least the bent region of the flexible display; and
a plurality of engaging protrusions formed on the bendable member at a predetermined interval along a bending direction,
wherein the plurality of engaging protrusions become thinner as the engaging protrusions protrude further away from the bendable member, and
wherein the plurality of engaging protrusions are formed in an undercut shape enabling the plurality of engaging protrusions to penetrate through a guide slit formed on a target structure disposed parallel to a surface of the flexible display and then to be engaged with the target structure, and
wherein each of the plurality of engaging protrusions includes a tapered inclined surface tapering one side of an end furthest from the bendable member, the tapered inclined surface configured to minimize interference between engaging protrusions when the bendable member is bent.
