- the link side block 235 may include a side wall 2352 facing the side of the link 210 (in the vertical direction of the display device 100).
- the side wall 2352 may serve to support the link 210 so that it does not move in the vertical direction. Therefore, since the side wall 2352 and the link 210 are also in contact, the moving bar 233 may further include a protruding friction part 2332 on a surface facing the side wall 2352 as shown in FIG. .
- the entire link side block 235 may be made of polyacetal (POM: Poly Oxy Methylen), or only the surfaces 2351 and 2353 in contact with the friction part of the moving bar 233 may use polyacetal.
- POM Poly Oxy Methylen
- a stopper 238 protruding from the link side block 235 may be further included to limit the horizontal movement distance of the link 210 .
- the stopper 238 may be formed by protruding on the link side block 235, and as shown in FIG. 12, the stopper 238 protrudes from the fastening plate 237 and protrudes toward the link 210 through the link side block 235 It can be.
- the stopper 238 of this embodiment is formed only at a position to limit the movement distance of the link 210 when the display device 100 is bent, but is located outside the link 210 so that it can stop even when converted to a flat state A stopper 238 may be further included.
- the bracket cover 231 covering the link side block 235 can be configured and used to form a step on the outside of the moving bar 233 to replace the stopper 238 in the outward direction.
- the bracket cover 231 is a member that covers the link side block 235 and the fastening plate 237, and covers the link side block 235 and the fastening plate 237 so that screws fixing them are not exposed. As shown in FIG. 12, only a portion corresponding to the link 210 may be opened so that the link 210 can move.
- FIG. 14 is a view showing the arrangement of the link 210 and the link bracket 230 in a flat state and a curved state of the display device 100.
- the fastening plate 237 may be fastened to the main body 100' through the bracket fastener 236 at the end of the main body 100'.
- the horizontal end portion of the body 100' coupled with the rear surface of the body 100' is the first portion of the fastening plate 237, and the direction toward the horizontal center is the first portion of the fastening plate 237. It is called part 2.
- the angle ⁇ formed by the link bracket 230 on the rear surface of the display module 150 can be adjusted.
- the main body 100 ' is deformed into a curved surface having a predetermined curvature, but the curvature of the link 210 does not change and the arrangement direction changes. ') may be different from the angle of the horizontal end.
- the angle of the other end of the link 210 may have a steeper angle than the angle of the horizontal end of the main body 100' (a state in which the angle with the surface of the display module 150 in a flat state is tilted more). Therefore, when the entire surface including the second part of the link bracket 230 is fixed to the rear surface of the main body 100' with screws or the like, when the main body 100' is bent, a press mark may appear on the part where the link bracket 230 is coupled.
- the second part may not be fastened with the fastener 236.
- an inclined surface may be formed on the rear surface of the link bracket 230, that is, the rear surface of the link side block 235.
- An inclination (for example, about 2°) may be formed so that a region corresponding to the second portion protrudes further toward the rear surface. That is, the angle difference between the main body 100' and the link 210 can be compensated for because the inclination of the front and rear surfaces of the link side block 235 is different.
- the display module 150 can be deformed into a flat state or a bent state so that the user can use it in a desired form.
- durability of the display device 100 may be improved by using a material capable of minimizing wear due to friction generated during bending.
