A plurality of connection surfaces SF3a, SF3b, SF3c, SF3d, and SF3e may connect the first surface SF1 and the second surface SF2 together and define an internal space INS. As shown in the figure, at least some surfaces (e.g., connection surfaces SF3b and SF3d) of the plurality of connection surfaces SF3a, SF3b, SF3c, SF3d, and SF3e may each be a curved surface including a curve, and the remaining surfaces (e.g., connection surfaces SF3a, SF3c, and SF3e) may be flat surfaces. However, embodiments of the present disclosure are not limited thereto, and in another embodiment, a plurality of connection surfaces SF3a, SF3b, SF3c, SF3d, and SF3e may be provided as flat surfaces, and are not limited to any one embodiment of the present disclosure.

[0112] The shaft SFT may be accommodated in the internal space INS. The shaft SFT may extend in the first direction DR1. The shaft SFT may rotate about the first direction DR1. The display module DM described previously may be wound around or unwound from the shaft SFT according to the rotation of the shaft SFT. The shaft SFT may be rotated by rollers RL1 and RL2 to be described later, and rotated according to the extension or contraction of the support parts SP1 and SP2 in the second direction DR2.

[0113] For example, the pulling-in and pulling-out directions of the display module DM may intersect with the extending direction of the shaft SFT and may be arrangement directions of supports of the supports SP1 and SP2 to be described later in the first and second states.

[0114] The radius of the shaft SFT may be about 35 mm or less. Alternatively, the radius of the shaft SFT may be about 20 mm or less.

[0115] The display module DM may be the previously referenced Figures 2 to 6The display module DM is described, but the embodiments of the present disclosure are not limited thereto, and the display module DM may be provided in various forms.

[0116] and Fig. 8A Compared with the display device in Figure 8B The display device in may also include a display module DM. At least a portion of the display module DM may be wound around the axis SFT. The display module DM may be wound around the axis SFT or unwound from the axis SFT along the rotation direction of the axis SFT. Specifically, in the first state described previously, the display module DM may be wound around the axis SFT, and in the second state, the display module DM that has been wound around the axis SFT may be unwound from the axis SFT in the second direction DR2. In addition, at least a portion of the display module DM may be accommodated in the internal space INS.

[0117] The display module DM may be supported by the support parts SP1 and SP2. Specifically, the display module DM may be supported by any one of the first support part SP1 and the second support part SP2. Referring to the drawings, one side of the display module DM may be supported by the first support part SP1, and the other side of the display module DM may be supported by the second support part SP2. Specifically, one side of the display module DM may be supported by a plurality of first supports SPB1 of the first support part SP1, and the other side (i.e., the opposite side) of the display module DM may be supported by a plurality of second supports SPB2 of the second support part SP2.

[0118] The contraction of the first supporting portion SP1 and the second supporting portion SP2 in the second direction DR2 in the first state may be different from the extension of the first supporting portion SP1 and the second supporting portion SP2 in the second direction DR2 in the second state. In the first state, the first supporting portion SP1 and the second supporting portion SP2 may contract in the second direction DR2, and in the second state, the first supporting portion SP1 and the second supporting portion SP2 may extend in the second direction DR2.

[0119] Specifically, in the second state, the support members of the first support portion SP1 and the support members of the second support portion SP2 may be arranged in a direction intersecting the extension direction of the axis SFT to support the display module DM. In addition, in the first state, the support members of the first support portion SP1 and the support members of the second support portion SP2 may be arranged in a direction different from the extension direction of the axis SFT. That is, in the second state, the arrangement direction of the support members of the first support portion SP1 may be the same as the arrangement direction of the support members of the second support portion SP2. In the first state, the support members of the first support portion SP1 and the support members of the second support portion SP2 may be accommodated in the internal space INS.

[0120] According to an embodiment of the present disclosure, at least one of the display module DM and the support part SP1 or SP2 may include a magnetic substance. Since the display module DM and the support part SP1 or SP2 include a magnetic substance, the display module DM and the support part SP1 or SP2 may be in close contact with each other by a magnetic force generated between the display module DM and the support part SP1 or SP2. Alternatively, the magnetic substance may be disposed under the display module DM and included in the support part SP1 or SP2, and is not limited to any one embodiment of the present disclosure.

[0121] The first support portion SP1 and the second support portion SP2 may include a plurality of support members SPB1 and a plurality of support members SPB2, respectively. For example, the first support portion SP1 may include a plurality of first support members SPB1, and the second support portion SP2 may include a plurality of second support members SPB2. The first support member SPB1 and the second support member SPB2 may be provided in the same shape, but different in arrangement position and arrangement manner, but the embodiments of the present disclosure are not limited thereto. The first support member SPB1 and the second support member SPB2 may be provided in various shapes, and the shapes are not limited to any one embodiment of the present disclosure. The display module DM and the first support member SPB1 or the second support member SPB2 may include a magnetic substance.

[0122] Referring to the drawings, in the second state, the first support SPB1 may be arranged in the second direction DR2, and the second support SPB2 may be arranged in the second direction DR2.

[0123] The first supporting portion SP1 and the second supporting portion SP2 may each be pulled out or pulled in through the inlet portion OP. The first supporting portion SP1 and the second supporting portion SP2 may each be accommodated in the internal space INS through the inlet portion OP. For example, the first supporting portion SP1 may be accommodated in the first accommodating portion ACP1 while being pulled into the housing HS, and the second supporting portion SP2 may be accommodated in the second accommodating portion ACP2 while being pulled into the housing HS.

[0124] According to an embodiment of the present disclosure, in a first state in which the display module DM is wound around the axis SFT, the first supporting portion SP1 and the second supporting portion SP2 may be retracted in the second direction DR2 to be accommodated in the shell HS, and, in a second state in which the display module DM is unwound from the axis SFT and pulled out of the shell HS to be exposed, the first supporting portion SP1 and the second supporting portion SP2 may be extended in the second direction DR2 to support the display module DM.

[0125] In the first state, the first support portion SP1 can be accommodated in the first accommodation portion ACP1 in the internal space INS, and the second support portion SP2 can be accommodated in the second accommodation portion ACP2 in the internal space INS. In other words, the first support member SPB1 of the first support portion SP1 can be accommodated in the first accommodation portion ACP1, and the second support member SPB2 of the second support portion SP2 can be accommodated in the second accommodation portion ACP2. FIG. 10A to FIG. 10C This is described in detail.

[0126] Referring to the drawings, in the second state, the first support SPB1 may be arranged in the second direction DR2, and the second support SPB2 may be arranged in the second direction DR2.

[0127] The first support member SPB1 may include a first support portion SPP1a and a second support portion SPP2a, and the second support member SPB2 may include a first support portion SPP1b and a second support portion SPP2b. In a plan view, each of the first support portions SPP1a and SPP1b may overlap with the display module DM, and each of the second support portions SPP2a and SPP2b may not overlap with the display module DM. For example, the first support portion SPP1a of the first support member SPB1 and the first support portion SPP1b of the second support member SPB2 may support the display module DM, the second support portion SPP2a of the first support member SPB1 may contact the first roller RL1, and the second support portion SPP2b of the second support member SPB2 may contact the second roller RL2.

[0128] The first roller RL1 and the second roller RL2 may be coupled to the shaft SFT. For example, the first roller RL1 may be coupled to one side of the shaft SFT, and the second roller RL2 may be coupled to the other side of the shaft SFT. The first roller RL1 and the second roller RL2 may be spaced apart from each other in the first direction DR1. The first roller RL1 and the second roller RL2 may each rotate about the first direction DR1. The first roller RL1 and the second roller RL2 may each extend along the first direction DR1.

[0129] The first roller RL1 and the second roller RL2 may rotate according to the contraction or extension of the first support portion SP1 and the second support portion SP2 in the second direction DR2. The first roller RL1 and the second roller RL2 may contact the first support portion SP1 and the second support portion SP2, respectively. Through the contact of the first roller RL1 with the first support portion SP1 and through the contact of the second roller RL2 with the second support portion SP2, the first roller RL1 and the second roller RL2 may rotate according to the contraction or extension of the first support portion SP1 and the second support portion SP2 in the second direction DR2, respectively. For example, the linear motion of the first support portion SP1 may be changed into the rotational motion of the first roller RL1 due to the meshing structure (e.g., gear structure) of the first roller RL1 and the first support portion SP1. However, the embodiments of the present disclosure are not limited thereto, and in another embodiment, the linear motion of the first support portion SP1 may be changed into the rotational motion of the first roller RL1 by the magnetic force applied between the first roller RL1 and the first support portion SP1, and the change of motion is not limited to any one embodiment of the present disclosure. The above description is equally applicable to the second roller RL2 and the second supporting portion SP2.

[0130] According to an embodiment of the present disclosure, the first roller RL1 and the second roller RL2 may rotate as the first support portion SP1 and the second support portion SP2 are pulled into or out of the housing HS, respectively. Figure 2 ) by movement, the first support member SPB1 of the first support portion SP1 or the second support member SPB2 of the second support portion SP2 can be respectively pulled into or pulled out of the shell HS.

[0131] In such a relationship between the first support portion SP1 and the first roller RL1 and the relationship between the second support portion SP2 and the second roller RL2, the linear motion of the support portions SP1 and SP2 can be changed into the rotational motion of the rollers RL1 and RL2, respectively. Thus, a separate power unit for rotating the shaft SFT is not additionally required, and thus it can be beneficial to miniaturization of the display device. For example, the outer diameter of the shaft SFT can be reduced.

[0132] However, in order to facilitate the rotation of the shaft SFT, a separate power unit or the like may be provided to the inside of the housing HS or the outside of the housing HS, and is not limited to any one embodiment of the present disclosure.

[0133] The first roller RL1 and the second roller RL2 may be coupled to the shaft SFT, and at this time, the shaft SFT may also rotate with the rotation of the first roller RL1 and the second roller RL2. According to the rotation of the shaft SFT, the display module DM may be wound around the shaft SFT or unwound from the shaft SFT. At this time, whether the display module DM is wound around the shaft SFT or unwound from the shaft SFT depends on whether the first support SPB1 and the second support SPB2 are pulled into the housing HS or pulled out from the housing HS. For example, when the first support SPB1 and the second support SPB2 are pulled into the housing HS, the rollers RL1 and RL2 may rotate, and the display module DM may be wound around the shaft SFT. When the first support SPB1 and the second support SPB2 are pulled out from the housing HS, the rollers RL1 and RL2 may rotate, and the display module DM may be unwound from the shaft SFT. That is, according to the rotation of the first and second rollers RL1 and RL2 caused by the first and second supports SPB1 and SPB2 being pulled in or out, the display module DM may be wound around or unwound from the shaft SFT to be accommodated in the internal space INS or exposed to the outside of the internal space INS.

[0134] The housing HS may include a first accommodation portion ACP1 and a second accommodation portion ACP2. The first accommodation portion ACP1 and the second accommodation portion ACP2 may be defined in an internal space INS of the housing HS. The first accommodation portion ACP1 and the second accommodation portion ACP2 may be spaced apart from each other. The first support portion SP1 may be accommodated in the first accommodation portion ACP1, and the second support portion SP2 may be accommodated in the second accommodation portion ACP2.

[0135] According to an embodiment of the present disclosure, the first support portion SP1 may be arranged along the first accommodating portion ACP1, and the second support portion SP2 may be arranged along the second accommodating portion ACP2. Specifically, the first support member SPB1 of the first support portion SP1 may be arranged along the first accommodating portion ACP1, and the second support member SPB2 of the second support portion SP2 may be arranged along the second accommodating portion ACP2.

[0136] In the first accommodating portion ACP1, some of the first supports SPB1 may be arranged in the same direction, and the rest of the first supports SPB1 may be arranged in different directions. In the second accommodating portion ACP2, some of the second supports SPB2 may be arranged in the same direction, and the rest of the second supports SPB2 may be arranged in different directions. FIG. 10A to FIG. 10C The arrangement of the first support SPB1 in the first accommodating portion ACP1 and the second support SPB2 in the second accommodating portion ACP2 is described.

[0137] The first receiving portion ACP1 and the second receiving portion ACP2 may be disposed on the same surface. Referring to the accompanying drawings, the first receiving portion ACP1 and the second receiving portion ACP2 may be disposed on the first surface SF1. However, the embodiments of the present disclosure are not limited thereto, and in another embodiment, the first receiving portion ACP1 and the second receiving portion ACP2 may be disposed on the third surface SF3, and the positions are not limited to any one embodiment of the present disclosure.

[0138] The first accommodating portion ACP1 and the second accommodating portion ACP2 may be arranged to be separated from each other by different distances relative to the axis SFT. Referring to the accompanying drawings, the second accommodating portion ACP2 may be arranged to be further separated from the axis SFT when the first accommodating portion ACP1 is between the second accommodating portion ACP2 and the axis SFT. However, the embodiments of the present disclosure are not limited to those shown in the drawings, and the first accommodating portion ACP1 may be arranged to be further separated from the axis SFT when the second accommodating portion ACP2 is between the first accommodating portion ACP1 and the axis SFT, and the arrangement thereof is not limited to any one embodiment of the present disclosure. In addition, the first accommodating portion ACP1 and the second accommodating portion ACP2 may be arranged to be separated from each other by the same distance relative to the axis SFT.

[0139] The first receiving portion ACP1 may be defined by the first dividing member DVM1 and the second dividing member DVM2. An extending direction of the first dividing member DVM1 and an extending direction of the second dividing member DVM2 may be different from each other.

[0140] Referring to the drawings, the first dividing member DVM1 may extend in the first direction DR1, and the second dividing member DVM2 may be connected to one side of the first dividing member DVM1. In addition, the second dividing member DVM2 may extend in a direction different from the first direction DR1. For example, the second dividing member DVM2 may extend in the second direction DR2. However, the embodiments of the present disclosure are not limited thereto, and in another embodiment, a portion of the second dividing member DVM2 may extend in the second direction DR2, another portion may extend in the first direction DR1, and a portion of the second dividing member DVM2 may be curved.

[0141] The first support member SPB1 may be arranged along the first dividing member DVM1 and the second dividing member DVM2. Fig. 10B Describe the details.

[0142] The second accommodation portion ACP2 may be defined by a third dividing member DVM3 and a fourth dividing member DVM4. The extension direction of the third dividing member DVM3 and the extension direction of the fourth dividing member DVM4 may be different from each other. Referring to the accompanying drawings, the third dividing member DVM3 may extend in a first direction DR1, and the fourth dividing member DVM4 may be connected to one side of the third dividing member DVM3. In addition, the fourth dividing member DVM4 may extend in a direction different from the first direction DR1. For example, the fourth dividing member DVM4 may extend in the second direction DR2. However, embodiments of the present disclosure are not limited thereto, and in another embodiment, a portion of the fourth dividing member DVM4 may extend in the second direction DR2, another portion may extend in the first direction DR1, and a portion of the fourth dividing member DVM4 may be curved.

[0143] The first dividing member DVM1 and the third dividing member DVM3 may be provided to correspond to each other. The second dividing member DVM2 and the fourth dividing member DVM4 may be provided to correspond to each other. For example, the first dividing member DVM1 and the third dividing member DVM3 may be consistent in shape, width, length, etc., but may differ only in arrangement position, and the second dividing member DVM2 and the fourth dividing member DVM4 may also be consistent in shape, width, length, etc., but may differ only in arrangement position. However, the embodiments of the present disclosure are not limited thereto, and the first dividing member DVM1, the second dividing member DVM2, the third dividing member DVM3, and the fourth dividing member DVM4 may have various shapes or widths and lengths.

[0144] The first support member SPB1 may be arranged along the first and second dividing members DVM1 and DVM2, and the second support member SPB2 may be arranged along the third and fourth dividing members DVM3 and DVM4. FIG. 10A to FIG. 10C Describe the details.

[0145] Reference Figure 8C , divided into components DVM1, DVM2, DVM3 and DVM4 (see Figure 8B ) can be provided in plural. Due to the division components DVM1, DVM2, DVM3 and DVM4 (see Figure 8B ) are provided in plural, so that the utilization of space can be increased not only for the relationship between the supports SPB1 and SPB2, but also for the relationship between other components in the housing HS.

[0146] The first dividing member DVM1 and the second dividing member DVM2 (see Figure 8B ) may each be provided in plural. A plurality of first dividing members DVM1 and second dividing members DVM2 (see Figure 8B) can be alternately arranged along the arrangement direction of the support member SPB1. The second dividing member DVM2 (see Figure 8B ) can connect the first partitioning members DVM1 spaced apart from each other (see Figure 8B ). Specifically, the first dividing members DVM1a, DVM1b, and DVM1c may extend in the first direction DR1, and the second dividing members DVM2a and DVM2b may each extend in a direction different from the first direction DR1 and may be connected to the first dividing members DVM1a and DVM1c. A portion of each of the second dividing members DVM2a and DVM2b may be bent. At least one of the second dividing members DVM2a and DVM2b may be disposed between adjacent first dividing members among the first dividing members DVM1a, DVM1b, and DVM1c.

[0147] The third dividing member DVM3 and the fourth dividing member DVM4 (see Figure 8B ) may each be provided in plural. A plurality of third dividing members DVM3 and fourth dividing members DVM4 (see Figure 8B ) may be alternately arranged along the arrangement direction of the support member SPB2. Figure 8B ) may connect the third dividing members DVM3 spaced apart from each other. Specifically, the third dividing members DVM3a, DVM3b, and DVM3c may extend along the first direction DR1, and the fourth dividing members DVM4a and DVM4b may each extend in a direction different from the first direction DR1 and may be connected to the third dividing members DVM3a and DVM3c. A portion of each of the fourth dividing members DVM4a and DVM4b may be bent. At least one of the fourth dividing members DVM4a and DVM4b may be disposed between adjacent third dividing members among the third dividing members DVM3a, DVM3b, and DVM3c.

[0148] For example, increasing the space in the shell HS that can accommodate the supports SPB1 and SPB2 can increase the number of supports SPB1 and SPB2 that can support the display module DM in the second state, and thus, in response to the increase in the size of the display module DM, it may be possible to accommodate the supports SPB1 and SPB2 in the shell HS.

[0149] In addition, as for the relationship between other components, miniaturization of the display device can be facilitated by minimizing the volumes of the first accommodating portion ACP1 and the second accommodating portion ACP2 accommodating the supports SPB1 and SPB2 while accommodating the same number of supports SPB1 and SPB2 in the housing HS.

[0150] Fig.9A and Fig. 9Bis an enlarged view showing a portion of a display device according to an embodiment of the present disclosure. Specifically, Fig.9A It is shown Fig. 8A an enlarged view of a portion of the display device, and Fig. 9B It is shown Figure 8B An enlarged view of a portion of the display device.

[0151] Reference Fig.9A and Fig. 9B The second roller RL2 may include a first gear GR1b, and the second supporting member SPB2 of the second supporting portion SP2 may include a second gear GR2b, and include a first supporting portion SPP1b and a second supporting portion SPP2b.

[0152] Fig.9A and Fig. 9B Only the second roller RL2 and the second support portion SP2 are shown, and the first roller RL1 and the first support portion SP1 are omitted, but the following description of the second roller RL2 and the second support portion SP2 is equally applicable to the first roller RL1 (see Fig. 8A ) and the first support portion SP1 (see Fig. 8A That is, like the second roller RL2, the first roller RL1 (see Fig. 8A ) may also include a first gear GR1a (see Fig. 8A ), and the first support portion SP1 (see Fig. 8A ) of the first support member SPB1 (see Fig. 8A ) may also each include a first support portion SPP1a (see Fig. 8A ) and the second support portion SPP2a (see Fig. 8A ).

[0153] The first gear GR1b of the second roller RL2 may be disposed along the outer periphery of the second roller RL2. The first gear GR1b of the second roller RL2 may mesh with the second gear GR2b of the second support SPB2. When the linear motion of the second support SPB2 is changed into the rotational motion of the second roller RL2 and the shaft SFT, the transmission of power may be facilitated by providing the first gear GR1b to the second roller RL2 and providing the second gear GR2b to the second support SPB2. By such an engagement structure of the gears, the transmission of power between the second support SPB2 and the second roller RL2 may be facilitated, and the loss of the transmitted power may be reduced. This may be equally applied to the first support SPB1 as previously described (see Fig. 8A ) and the first roller RL1 (see Fig. 8A ).

[0154] The thickness D1 of the first gear GR1b and the thickness D2 of the second gear GR2b may be the same. However, the embodiments of the present disclosure are not limited thereto, and in another embodiment, the thickness D2 of the second gear GR2b may be greater than the thickness D1 of the first gear GR1b, and the thickness is not limited to any one embodiment of the present disclosure.

[0155] The second support SPB2 may include a first support portion SPP1b contactable with the display module DM and a second support portion SPP2b having a second gear GR2b. Specifically, in the first state, the first support portion SPP1b may contact with the display module DM and may support the display module DM.

[0156] The second supporting portion SPP2b of the second support SPB2 may be spaced further apart from the display module DM than the first supporting portion SPP1b. Alternatively, in a plan view, the second supporting portion SPP2b may not overlap with the display module DM.

[0157] The area of ​​the second supporting portion SPP2b may be smaller than the area of ​​the first supporting portion SPP1b. In other words, the length D2 of the second supporting portion SPP2b in the first direction DR1 may be smaller than the length D3 of the first supporting portion SPP1b in the first direction DR1. By making the area of ​​the second supporting portion SPP2b smaller than the area of ​​the first supporting portion SPP1b, the area of ​​the second supporting portion SPP2b surrounding the display module DM may be minimized. However, the embodiments of the present disclosure are not limited thereto, and in another embodiment, the area of ​​the first supporting portion SPP1b may be the same as the area of ​​the second supporting portion SPP2b, and the area is not limited to any one embodiment of the present disclosure.

[0158] and Fig.9A Compared with the display device in Fig. 9B The display device in the embodiment further includes a display module DM. At least a portion of the display module DM may be rolled around the axis SFT. In addition, the display module DM may be supported by the second supporting portion SPP2b.

[0159] Referring to the drawings, the display module DM is supported by the first support portion SPP1b and is not supported by the second support portion SPP2b. As previously described, in a plan view, the second support portion SPP2b does not overlap with the display module DM. When the second gear GR2b of the second support portion SPP2b is engaged with the first gear GR1b of the second roller RL2, as previously described, the linear motion of the second support member SPB2 can be changed into the rotational motion of the second roller RL2 and the shaft SFT. This is equally applicable to the first support member SPB1 described previously (see Fig. 8A ) and the first roller RL1 (see Fig. 8A ).

[0160] Fig. 10A is a perspective view of a display device according to an embodiment of the present disclosure, Fig. 10B is an enlarged view of a portion of a display device according to an embodiment of the present disclosure, and Fig. 10C is a cross-sectional view of a display device according to an embodiment of the present disclosure.

[0164] The first partitioning member DVM1 of the first accommodating portion ACP1 (see Figure 8B ) and a second partitioning member DVM2 (see Figure 8B ) may extend in different directions. The first support member SPB1 may extend along the first partitioning member DVM1 (see Figure 8B ) or the second dividing member DVM2 (see Figure 8B In other words, among the plurality of first support members SPB1, the first partitioning member DVM1 (see Figure 8B ) and the first support member SPB1 arranged along the second dividing member DVM2 (see Figure 8B ) The first support member SPB1 arranged in the embodiment of the present invention may be different in the arrangement direction.

[0165] The third partitioning member DVM3 (see Figure 8B) and the fourth dividing member DVM4 (see Figure 8B ) can extend in different directions. The second support member SPB2 can extend along the third dividing member DVM3 (see Figure 8B ) or the fourth dividing member DVM4 (see Figure 8B In other words, among the plurality of second support members SPB2, the third partitioning member DVM3 (see Figure 8B ) and along the fourth dividing member DVM4 (see Figure 8B ) The second support member SPB2 arranged in the embodiment of the present invention may be different in the arrangement direction.
