[0043] The moving block 134 may be located inside the flip frame 133. The moving block 134 may be located between the first frame 133a and the second frame 133b of the flip frame 133.

[0044] The lead screw 135 is inserted into the moving block 134. The moving block 134 can move on the lead screw 135 by the rotation of the lead screw 135. When the lead screw 135 rotates and counter-rotates, the moving block 134 can reciprocate on the lead screw 135.

[0045] The lead screw 135 is coupled to the drive gear 136 and rotates together with the drive gear 136. The drive gear 136 faces the rear surface of the plate 120 (see FIG. 2) and can rotate. The lead screw 135 may be a rotation shaft of the drive gear 136. The bearing B may be coupled to one end and / or both ends of the lead screw 135. One end of the lead screw 135 is inserted into the front bearing B and rotates, and the other end of the lead screw 135 is inserted into the rear bearing B and rotates. For example, the lead screw 135 may be press-fitted into the front bearing B and the rear bearing B.

[0046] The motor 137 is located below the moving block 134. The motor 137 provides rotational power. The gear box 138 transmits the rotational force of the motor 137 to the drive gear 136.

[0047] 4 and 5, the first gear 138a is fixed to a rotating shaft 137a of the motor 137 and rotates together with the rotating shaft 137a of the motor 137.

The moving block 134 includes a moving body 134a and a sliding block 134b. For example, the moving body 134a may be made of metal, and the sliding block 134b may be made of synthetic resin. The sliding block 134b is located inside the moving body 134a. The sliding block 134b may be screw-coupled to the lead screw 135.

[0051] The lead screw 135 may be inserted into the sliding block 134b. As the lead screw 135 rotates, the sliding block 134b may move on the lead screw 135. A play may be formed between an inner peripheral surface of the sliding block 134b and a screw 135b of the lead screw 135. This can prevent the moving block 134 from being stopped while moving on the lead screw 135 or from being locked during movement.

[0052] 7, the moving body 134a includes an outer part 134a1 and an inner part 134a2. The outer part 134a1 forms the outer surface of the moving body 134a. The inner part 134a2 is coupled to the inside of the outer part 134a1. For example, the outer part 134a1 may be a U-shaped metal plate, and the inner part 134a2 may be a metal shell having an internal receiving space. The sliding block 134b may be coupled to the inside of the inner part 134a2.

[0053] The pivot pin 133c protrudes and extends from the outer part 134a1 of the moving body 134a. The first frame 133a and the second frame 133b of the flip frame 133 may include holes 133H1 and 133H2. The pivot pin 133c may be inserted into the hole 133H2 of the second frame 133b and the hole 133H1 of the first frame 133a. A disk 133d is located between the first frame 133a and the second frame 133b, and the pivot pin 133c may be inserted into the hole 133dH of the disk 133d. For example, the disk 133d may be made of a material having high durability and low friction.

[0054] The intermediate member 139 is located between the moving body 134a and the pivot pin 133c and the flip frame 133. The intermediate member 139 can cover the upper surface of the moving body 134a and the outer surface of the pivot pin 133c. The intermediate member 139 may be called a low-friction member 139 or a lubricating member 139. The intermediate member 139 may also be called a skin member 139.

[0055] The intermediate member 139 includes a body portion 139a and a flange portion 139b. The body portion 139a may be cylindrical. The pivot pin 133c may be inserted into the body portion 139a. The body portion 139a may contact the outer surface of the pivot pin 133c, and the flange portion 139b may contact the upper surface of the moving body 134a. The intermediate member 139 may be a synthetic resin having low friction. The intermediate member 139 may be a low friction material. For example, the intermediate member 139 may be a POM acetal homopolymer material. The first frame 133a and the second frame 133b of the flip frame 133 are in contact with or friction with the intermediate member 139 and can move around the pivot pin 133c.

[0056] The intermediate member 139 can fill the gap between the hole 133H1 of the first frame 133a of the flip frame 133 and the pivot pin 133c. The intermediate member 139 can fill the gap between the hole 133H2 of the second frame 133b of the flip frame 133 and the pivot pin 133c. The second frame 133b of the flip frame 133 is placed on the intermediate member 139. This allows the pivot pin 133c to transmit force to the flip frame 133 without noise or vibration.

[0057] 8 and 9, when the lead screw 135 rotates, the moving block 134 and the flip frame 133 can move on the lead screw 135. The flip frame 133 can perform reciprocating motion in the longitudinal direction of the lead screw 135. The movement of the flip frame 133 can cause the first wing 141 and / or the second wing 142 to pivot about pivot axes 141p and 142p.

[0058] A first distance (D1) from the pivot pin 133c to the pivot shafts 141p, 142p may be smaller than a second distance (D2) from the pivot shafts 141p, 142p to the sliding mounts 151, 152. For example, the first distance (D1) may be 1 / 4 of the second distance (D2). The levers 141c, 142c of the wings 141, 142 are fixed to the flip frame 133, and the driving force of the moving block 134 that moves on the lead screw 135 while the flip frame 133 moves with the operation of the pivot pin 133c can be efficiently transmitted to the levers 141c, 142c of the wings 141, 142 via the flip frame 133.

[0059] In addition, the levers 141c and 142c of the wings 141 and 142 are fixed to the flip frame 133 and move together to increase the first distance D1, so that the wings 141 and 142 can be driven with a small force. This increases the power transmission efficiency of the driving unit 130 and reduces the power consumption of the motor 137.

[0060] 10 and 11, the elastic member 101 includes a first part 101a, a second part 101b, and a third part 101c. The elastic member 101 may be called a first elastic member 101 or a clip 101. The first part 101a may be a plate. The second part 101b may be curved and extended from the first part 101a. The third part 101c may be curved and extended from the second part 101b. The third part 101c may face the first part 101a. A second angle formed by the second part 101b and the third part 101c may be larger than a first angle formed by the first part 101a and the second part 101b. In the extending direction, the length of the third part 101c may be larger than the length of the first part 101a. The elastic member 101 may be a metal plate and may have elasticity. For example, the elastic member 101 may be a leaf spring.

[0061] The coupling hole 101H1 may be formed in the first part 101a. There may be multiple coupling holes 101H1. The support rib 101R may be formed in the third part 101c. The support rib 101R extends long in the extension direction of the third part 101c. There may be multiple support ribs 101R. The support rib 101R protrudes from the outer surface of the third part 101c. The multiple support ribs 101R may be parallel to each other.

[0062] The elastic member 101 is inserted between the moving block 134 and the levers 141c, 142c of the wings 141, 142. The first part 101a of the elastic member 101 is fixed to the levers 141c, 142c of the wings 141, 142. For example, the first part 101a of the elastic member 101 is fastened to the levers 141c, 142c of the wings 141, 142 by a screw. The third part 101c of the elastic member 101 supports the moving block 134. The third part 101c of the elastic member 101 contacts the side of the moving block 134. The third part 101c of the elastic member 101 contacts the outer part 134a1 and / or the inner part 134a2 of the moving body 134a. The outer part 134a1 and / or the inner part 134a2 of the moving body 134a, which contacts the third part 101c of the elastic member 101, may be rounded. The support rib 101R formed on the third part 101c of the elastic member 101 contacts the inner part 134a2 of the moving block 134.

[0063] There may be a plurality of elastic members 101. Each of the plurality of elastic members 101 may be inserted between the moving block 134 and the lever 141c of the first wing 141 and between the moving block 134 and the lever 142c of the second wing 142.

[0064] In the mechanism in which the flip frame 133 flips or pivots around the pivot pin 133c, play occurs between the pivot pin 133c of the moving block 134 and the holes 133H1 and 133H2 (see FIG. 7) of the flip frame 133. The elastic member 101 can push the moving block 134 in one direction. The elastic member 101 can push the moving block 134 in one direction so that the pivot pin 133c of the moving block 134 can be in close contact with one side of the holes 133H1 and 133H2 of the flip frame 133.

[0065] Accordingly, in all sections where the moving block 134 moves in the lead screw 135, force can be transmitted to the flip frame 133. In the mechanism where the moving block 134 transmits force to the flip frame 133, play between components may cause a phenomenon where the bending of the display panel 110 temporarily stops. According to this embodiment, continuous bending of the display panel 110 can be realized.

[0066] Referring to FIGS. 12 and 13, the elastic member 102 may include a lever portion 102a, support portions 102d, 102e, and coil portions 102b, 102c. The elastic member 102 may be formed of a wire. The elastic member 102 may also be referred to as a second elastic member 102.

[0067] The lever portion 102a may be a wire bent in a U shape. The coil portions 102b, 102c are connected to the lever portion 102a. There may be a plurality of coil portions 102b, 102c. The first coil portion 102b is connected to one end of the lever portion 102a, and the second coil portion 102c is connected to the other end of the lever portion 102a. There may be a plurality of support portions 102d, 102e. The first support portion 102d forms the end of the first coil portion 102b, and the second support portion 102e forms the end of the second coil portion 102c.

[0068] When the support portions 102d, 102e are fixed, the lever portion 102a can rotate or pivot about the coil portions 102b, 102c. The coil portions 102b, 102c provide an elastic force to the lever portion 102a.

[0069] The elastic member 102 may be installed on the wing bracket 132. The support portions 102d, 102e of the elastic member 102 are fixed to the bracket frame 132a of the wing bracket 132. The lever portion 102a of the elastic member 102 can be supported by the lever 142c of the wing 142.

[0070] The wing 142 may include a support groove 142c2 and a friction pad 142c1. The support groove 142c2 may be formed at a position corresponding to a portion of the length of the lever portion 102a of the elastic member 102. The friction pad 142c1 may be formed in the support groove 142c2. The friction pad 142c1 may be formed to protrude from the support groove 142c2, and the surface of the friction pad 142c1 may be polished smoothly.

[0071] When the wings 141 and 142 are pivotally coupled to the wing brackets 131 and 132, a play is formed between the pivot shafts 141p and 142p of the wings 141 and 142 and the wing holders 131b and 132b of the wing brackets 131 and 132. In a mechanism in which the moving block 134 transmits a force to the flip frame 133 and the wings 141 and 142 bend the display panel 110, the play between the components causes a phenomenon in which bending of the display panel 110 stops temporarily. The wings 141 and 142 can receive a force from the elastic member 102 toward the front of the display device 100. This allows the bending of the display panel 110 to be continuously realized. In addition, the power consumption of the motor 137 for bending the display panel 110 can be reduced.

[0072] In addition, the threaded coupling between the sliding block 134b (see FIG. 6) and the lead screw 135 provides a play for the sliding block 134b to move on the lead screw 135. The elastic member 102 pushes the wings 141 and 142 to bring the sliding block 134b into close contact with one side of the lead screw 135, thereby enabling continuous bending of the display panel 110. In addition, if the rotational force of the motor 137 and the lead screw 135 is released when the display panel 110 is in a flat state, the flatness of the display panel 110 may change. According to this embodiment, the display panel 110 can be maintained in a flat state and / or a state in which the display panel 110 is curved at a predetermined curvature.

[0073] 14 and 15 together with FIG. 8, when the wings 141, 142 are pivotally coupled to the wing brackets 131, 132, play is formed between the pivot shafts 141p, 142p of the wings 141, 142 and the wing holders 131b, 132b of the wing brackets 131, 132. In the mechanism in which the moving block 134 transmits force to the flip frame 133 and the wings 141, 142 bend the display panel 110, the play between the components may cause a phenomenon in which bending of the display panel 110 temporarily stops.

[0074] The elastic rings 103, 104 are positioned around the outer circumference of the lead screw 135. The lead screw 135 may be inserted into the elastic rings 103, 104. The elastic rings 103, 104 may be referred to as compression rings 103, 104 or compression members 103, 104. For example, the elastic rings 103, 104 may be made of highly elastic rubber. The diameter of the elastic rings 103, 104 may be larger than the diameter of the shaft body 135a of the lead screw 135. For example, the inner diameter of the elastic rings 103, 104 may be larger than the outer diameter of the shaft body 135a of the lead screw 135. The elastic rings 103, 104 may be multiple. The multiple elastic rings 103, 104 include a first elastic ring 103 and a second elastic ring 104. The first elastic ring 103 may be referred to as a front elastic ring 103, and the second elastic ring 104 may be referred to as a rear elastic ring 104.

[0075] The front elastic ring 103 is located between the driving gear 136 and the moving block 134. The front elastic ring 103 contacts the driving gear 136. While the moving block 134 moves on the lead screw 135, the front elastic ring 103 contacts or separates from the inner part 134a2 of the moving block 134. As the moving block 134 approaches the driving gear 136, the front elastic ring 103 can be compressed. Also, when the moving block 134 moves away from the driving gear 136, the front elastic ring 103 can push the moving block 134.

[0076] The rear elastic ring 104 is located between the bearing B and the moving block 134. The rear elastic ring 104 contacts the bearing B. While the moving block 134 moves on the lead screw 135, the rear elastic ring 104 can contact or separate from the outer part 134a1 of the moving block 134. As the moving block 134 approaches the bearing B, the moving block 134 can compress the rear elastic ring 104. Also, when the moving block 134 moves away from the bearing B, the rear elastic ring 104 can push the moving block 134.

[0077] This allows continuous bending of the display panel 110. Also, a large amount of power is required in the initial drive to bend or flatten the display panel 110. During the initial drive of the moving block 134, the elastic rings 103 and 104 push the moving block 134 to bend the display panel 110, thereby reducing the power consumption of the motor 137.

[0078] In addition, the threaded connection between the sliding block 134b (see FIG. 6) and the lead screw 135 can provide a play for the sliding block 134b to move on the lead screw 135. The moving block 134 compresses the elastic rings 103, 104, or the elastic rings 103, 104 push the moving block 134, so that the sliding block 134b comes into close contact with the lead screw 135 in the longitudinal direction of the lead screw 135, and bending of the display panel 110 can be continuously realized.

[0079] In addition, if the rotational force of the motor 137 or the lead screw 135 is released when the display panel 110 is flat, the flatness of the display panel 110 may change. According to the present embodiment, the display panel 110 can be maintained in a flat state and / or in a state where the display panel 110 is curved at a predetermined curvature.

[0080] 16, the flip frame 133 includes holes 133H1 and 133H2. The holes 133H1 and 133H2 are located adjacent to the ends of the first frame 133a and / or the second frame 133b of the flip frame 133. The holes 133H1 and 133H2 may be long holes 133H1 and 133H2 having a long axis and a short axis. The long axes of the holes 133H1 and 133H2 may be parallel to the longitudinal direction of the frame 133. The short axes of the holes 133H1 and 133H2 may intersect with the longitudinal direction of the frame 133.

[0081] 17 to 19, the pivot pin 133c is inserted into holes 133H1 and 133H2 of the flip frame 133, and the moving block 134 can move on the lead screw 135. As the moving block 134 moves on the lead screw 135, the display panel 110 can be curved from a flat state (see FIG. 17) (see FIG. 18) and can be curved at a certain curvature (see FIG. 19).

[0082] The direction of movement of the moving block 134 may change when the display panel 110 starts to curve from a flat state, or when the display panel 110 curves with a predetermined curvature and then flattens as the radius of curvature becomes larger than the predetermined radius of curvature. That is, at the start and end points of the moving block 134, the display panel 110 may be flat or curved with a predetermined curvature.

[0083] When the moving block changes its moving direction at the start point and / or end point, it may change the direction in which the pivot pin 133c applies force to the holes 133H1 and 133H2 of the flip frame 133. When the pivot pin 133c changes the direction in which it applies force to the holes 133H1 and 133H2 of the flip frame 133, the play between the pivot pin 133c and the holes 133H1 and 133H2 of the flip frame 133 may cause the continuity of the change in curvature of the display panel 110 to be disrupted.

[0084] 20 and 21, the major axes of the holes 133H1 and 133H2 of the flip frame 133 may form an angle (theta) with respect to the longitudinal direction of the flip frame 133. For example, the angle (theta) may correspond to the angle (theta) formed by the start point or end point of the moving block 134 based on a line connecting the pivot shafts 141p and 142p of the wings 141 and 142 (see FIG. 8) around the pivot shafts 141p and 142p of the wings 141 and 142.

[0085] As the holes 133H1, 133H2 of the flip frame 133 approach the start or end point of the moving block 134, the major axes of the holes 133H1, 133H2 become parallel to a reference line connecting the pivot shafts 141p, 142p of the wings 141, 142 of the moving block 134. When the pivot pin 133c changes its moving direction, the moving direction of the pivot pin 133c is aligned with the minor axis direction of the holes 133H1, 133H2 of the flip frame 133.

[0086] At the moment when the pivot pin 133c changes its moving direction, if the moving direction of the pivot pin 133c is aligned with the minor axis of the holes 133H1 and 133H2 of the flip frame 133, it is possible to minimize the play formed between the pivot pin 133c and the holes 133H1 and 133H2 of the flip frame 133. This allows the pivot pin 133c to continuously transmit power or force to the flip frame 133 as the moving block 134 moves and / or changes direction.

[0087] 22 and 23, the first sliding mount 151 is fixed to the rear surface of the plate 120 adjacent to a first short side SS1 of the plate 120. The second sliding mount 152 is fixed to the rear surface of the plate 120 adjacent to a second short side SS2 of the plate 120.

[0088] The driving module 130 is located between the first sliding mount 151 and the second sliding mount 152, and is coupled to the rear surface of the plate 120. One end of the first wing 141 is pivotally coupled to the driving module 130, and the other end is coupled to the first sliding mount 151. The other end of the first wing 141 can move on the first sliding mount 151. One end of the second wing 142 is pivotally coupled to the driving module 130, and the other end is coupled to the second sliding mount 152. The other end of the second wing 142 can move on the second sliding mount 152.

[0089] The PCB plate 159 is located at the rear of the driving module 130. The PCB plate 159 is fixed to a rear bracket 130R (see FIG. 2) of the driving module 130. A PCB board can be coupled to the PCB plate 159.

[0090] The side cover 200 may form a wall around the side of the driving module 130. For example, the side cover 200 may be a square frame. A back cover (not shown) may cover the driving module 130 and be coupled with the side cover 200.

[0091] The slide bracket 160 is fixedly connected to ends of the wings 141 and 142. The slide bracket 160 includes a body 161 in the shape of an elongated plate and protrusions 162 and 163 formed adjacent to both ends of the body 161. The protrusions 162 and 163 may be referred to as friction protrusions 162 and 163 or contact protrusions 162 and 163. For example, the slide bracket 160 may be made of metal.

[0092] The protrusions 162, 163 may be multiple. The multiple protrusions 162, 163 include a front protrusion 163 and a rear protrusion 162. The front protrusion 163 may be formed at the first corner C1 and / or the fourth corner C4 of the body 161. The front protrusion 163 is pressed and protruded forward of the body 161. The front protrusion 163 may have a dome or hemispherical shape. The rear protrusion 162 may be formed at the second corner C2 and / or the third corner C3 of the body 161. The rear protrusion 162 is pressed and protruded rearward of the body 161. The rear protrusion 162 may have a dome or hemispherical shape. The rear protrusion 162 is adjacent to the front protrusion 163. The front protrusion 163 and the rear protrusion 162 are sequentially arranged along the short side of the body 161. The first pair of front protrusions 163 and rear protrusions 162 face the first pair of front protrusions 163 and rear protrusions 162 with respect to the wings 141, 142.

[0093] 24 and 25, the slide bracket 160 is coupled with the guide cover 170. The slide bracket 160 is inserted into the guide cover 170 and can move in the guide cover 170. For example, the guide cover 170 may be a synthetic resin having low friction. The guide cover 170 may be a low friction material. For example, the guide cover 170 may be a POM acetal homopolymer material.

[0094] The guide cover 170 includes a base 171, a side rail 172, and a fixing plate 173. The base 171 has a long extended plate shape and faces the slide bracket 160. The side rails 172 are formed on both ends of the base 171. The side rails 172 include a lower part 172L and an upper part 172U. The lower part 172L may extend from the base 171.

[0095] The lower part 172L may be formed with a lower trench 172LT. The lower trench 172LT is formed in the lower part 172L by recessing the upper surface of the lower part 172L inwardly. For example, the lower trench 172LT may be in a half-pipe shape. The front protrusion 163 of the slide bracket 160 may move on the lower trench 172LT. The radius of curvature of the front protrusion 163 may be smaller than the radius of curvature of the lower trench 172LT. This allows the front protrusion 163 to come into point contact with the lower trench 172LT.

[0096] The upper part 172U is spaced apart from the lower part 172L and faces the lower part 172L. A gap is formed between the upper part 172U and the lower part 172L, and the slide bracket 160 can be inserted into the gap. The upper part 172U can be formed with an upper trench 172UT. The upper trench 172UT is formed in the upper part 172U by a lower surface of the upper part 172U being recessed inwardly for a long distance. For example, the upper trench 172UT may have a half-pipe shape. The rear protrusion 162 of the slide bracket 160 can move on the upper trench 172UT. The radius of curvature of the rear protrusion 162 may be smaller than the radius of curvature of the upper trench 172UT. This allows the rear protrusion 162 to come into point contact with the upper trench 172UT.

[0097] The slide bracket 160 and the guide cover 170 are coupled together to prevent the wings 141 and 142 from sagging due to their own weight.

[0098] The slide bracket 160 may include a coupling portion 161a and a PEM nut 161b or a coupling protrusion 161b for coupling with the wings 141 and 142. The guide cover 170 may include a PEM nut 170b or a coupling protrusion 170b for coupling with the sliding mounts 151 and 152.

[0099] 26 to 28, the slide bracket 160 is coupled to the front of the wing blades 141a, 142b adjacent to the ends of the wings 141, 142. The guide cover 170 may be fixed to the sliding mounts 151, 152. The slide bracket 160 is inserted into the guide cover 170 and may move back and forth in the longitudinal direction of the wings 141, 142 within the guide cover 170.

[0100] When the display panel 110 is curved at a predetermined curvature and then flattened, the slide bracket 160 can move in the guide cover 170 toward the short sides SS1 and SS2 of the plate 120. The front protrusion 163 can move in the lower wrench 172LT. The front protrusion 163 can move in the lower wrench 172LT while making contact with or smoothly rubbing against the surface of the lower wrench 172LT. The rear protrusion 162 can move in the upper wrench 172UT while making contact with or smoothly rubbing against the surface of the upper wrench 172UT.

[0101] When the display panel 110 is flattened and then curved with a predetermined curvature, the slide bracket 160 can move in the guide cover 170 from the short sides SS1 and SS2 of the plate 120 toward the driving module 130. The front protrusion 163 can move in the lower wrench 172LT. The front protrusion 163 can move in the lower wrench 172LT while contacting or smoothly rubbing against the surface of the lower wrench 172LT. The rear protrusion 162 can move in the upper wrench 172UT while contacting or smoothly rubbing against the surface of the upper wrench 172UT.

[0102] The protrusions 162, 163 and the trenches 172LT, 172UT are in point contact to reduce friction, improving wear caused by friction. Also, since no lubricant is required, the structural durability of the mechanism can be improved.

[0103] 29, the lower trench 172LT includes a first inclined surface 172a and a second inclined surface 172b, and the upper trench 172UT includes a third inclined surface 172c and a fourth inclined surface 172d. The first inclined surface 172a forms a first angle (theta1) with respect to the base surface LB. The second inclined surface 172b forms a second angle (theta2) with respect to the base surface LB. The second inclined surface 172b can be in contact with the first inclined surface 172a.

[0104] The third inclined surface 172c forms a third angle (theta3) with respect to the base surface UB. The fourth inclined surface 172d forms a fourth angle (theta4) with respect to the base surface UB. The fourth inclined surface 172d may be tangent to the third inclined surface 172c. The boundary between the third inclined surface 172c and the fourth inclined surface 172d corresponds to or is aligned with the boundary between the first inclined surface 172a and the second inclined surface 172b. For example, the boundary between the third inclined surface 172c and the fourth inclined surface 172d may be aligned on the same line in the vertical direction as the boundary between the first inclined surface 172a and the second inclined surface 172b.

[0105] The second angle (theta2) may be greater than the first angle (theta1). The third angle (theta3) may be greater than the fourth angle (theta4). The length of the first inclined surface 172a may be greater than the length of the second inclined surface 172b. The length of the fourth inclined surface 172d may be greater than the length of the third inclined surface 172c. The third inclined surface 172c faces the first inclined surface 172a, and the second inclined surface 172b faces the fourth inclined surface 172d.

[0106] 30 in conjunction with FIG. 26, the slide bracket 160 to which the wing 140 is coupled is inserted or coupled to the guide cover 170 and the sliding mounts 151, 152. When the wings 151, 152 pivot about the drive module 130, the slide bracket 160 can move in the longitudinal direction of the wing 140 in the guide cover 170.

[0107] When the wings 140 curve the flat display panel 110, the sliding bracket 160 can move from the first inclined surface 172a to the second inclined surface 172b. When the wings 140 flatten the display panel 110 that is curved to a predetermined curvature, the sliding bracket 160 can move from the second inclined surface 172b to the first inclined surface 172a.

[0108] 27, while the wing 140 curves the flat display panel 110, the front protrusion 163 of the slide bracket 160 can slide while making contact with the lower wrench 172LT. The front protrusion 163 presses and rubs against the lower wrench 172LT. The rear protrusion 162 can slide while making contact with the upper wrench 172UT or can slide while being supported by the upper wrench 172UT.

[0109] While the wings 140 flatten the curved display panel 110 at a predetermined curvature, the front protrusion 163 of the slide bracket 160 can slide while contacting the lower wrench 172LT or can slide while being supported by the lower wrench 172LT. The rear protrusion 162 can slide while contacting the upper wrench 172UT or can slide while being supported by the upper wrench 172UT.

[0110] This allows the display panel 110 to be curved such that the curved curvature is constant or close to a constant curvature at a given curvature.

[0111] 31 to 33, the blades 141a and 142a of the wings 141 and 142 include palm portions 141A1 and 142A1. The palm portions 141a1 and 142a1 are formed on the front surfaces of the blades 141a and 142a adjacent to the ends of the blades 141a and 142a of the wings 141 and 142. The recesses 141a2 and 142a2 are formed in the palm portions 141a1 and 142a1. For example, the recesses 141a2 and 142a2 may be recessed inwardly of the palm portions 141a1 and 142a1 in a half-pipe shape, or may be formed by removing the palm portions 141a1 and 142a1. The fastening portion P may be formed in the palm portions 141a1 and 142a1. The fastening portion P may be formed to protrude from the outer surfaces of the recesses 141a2, 142a2 of the palm portions 141a1, 142a1. For example, the fastening portion P may be a protruding nut.

[0112] The lower supporter 164 is located on the recesses 141a2, 142a2 of the palm portions 141a1, 142a1. The body 164a of the lower supporter 164 may be a curved plate. For example, the lower supporter 164 may be a synthetic resin, and the outer surface may have a low friction coefficient. As another example, the lower supporter 164 may be a crystal type thermoplastic. As another example, the lower supporter 164 may be a POM resin. The lower supporter 164 has a fastening hole 164b.
