[0174] Fig.17 is with Fig.11 A substantially corresponding cross-sectional view, and Fig.18 is with Fig.12 The corresponding cross-sectional view, and Fig.19 is with Fig.13 Basically corresponding cross-sectional view.

[0175] refer to Fig.17 , Fig.18 and Fig.19 When viewed in the second direction DR2, the support plate SPP and the support rod SB may be located in the rear surface of the display module DM (i.e., the opposite surface of the front surface of the display module DM adjacent to the edge of the first housing CS1). The support plate SPP may be connected to the second housing CS2, and both sides of the support portion SP opposite to each other in the second direction DR2 are respectively inserted into the first guide groove GG1 to move in the first direction DR1.

[0176] For example, the support plate SPP may be connected to the second shell CS2. Fig.19 As shown in the figure, both sides of the first support plate SPP1 opposite to each other in the second direction DR2 are respectively inserted into the connection grooves CG to be connected to the second shell CS2.

[0177] Fig.18 The state of the display device DD shown in may be a basic mode of the display device DD, in which the second body CS2 moves in a direction approaching the first body CS1 along the first direction DR1.

[0178] In the basic mode of the display device DD, both sides of the support plate SPP may be located in the first extension portion EX1. Fig.17As shown in the figure, the two sides of the second support plate SPP2 opposite to each other in the second direction DR2 are respectively inserted and located in the first extension part EX1. In the basic mode of the display device DD, the two sides of the support bar SB opposite to each other in the second direction DR2 can be respectively inserted and located in the second extension part EX2 and the curved part CVP.

[0179] According to the position of the aforementioned support portion SP, the display module DM can be accommodated in the first shell CS1 and the second shell CS2 in a folded state along the curved portion CVP. For example, the portion of the display module DM located on the support rod SB in the curved portion CVP can be folded. The portion of the display module DM located on the support plate SPP can be folded. Figure 1 The opening portion OP shown in FIG. 1 is exposed to the outside, and a portion of the display module DM located on the support bar SB may not be exposed to the outside.

[0180] The sub-support portion SSP may overlap a portion of the support portion SP to be located below the support portion SP. For example, the sub-support portion SSP may overlap a second support plate SPP2 that is a portion of the support plate SPP to be located below the second support plate SPP2.

[0181] refer to Fig.18 and Fig. 20 , the gear portion GA may rotate to move the support rod SB located in the curved portion CVP. For example, the teeth of the gear portion GA may be located between the support rods SB located in the curved portion CVP. According to the rotation of the gear portion GA, the teeth may push the support rod SB, and thus the support rod SB may be moved more easily.

[0182] Fig.21 Shows Fig.18 The extended mode of the display device shown in .

[0183] refer to Fig.21 For the extended mode of the display device DD, when the second housing CS2 moves away from the first housing CS1 in the first direction DR1, the support portion SP can move along the first guide groove GG1. For example, the first support plate SPP1 is connected to the second housing CS2 to move along the second housing CS2 in the first direction DR1, and the second support plate SPP2 and the support rod SB can move along the first guide groove GG1. The gear portion GA can rotate to move the support rod SB along the first guide groove GG1.

[0184] The second housing CS2 can be moved in various ways. For example, the second housing CS2 can be moved by a driving portion that rotates the gear portion GA. The gear portion GA can be rotated in a clockwise direction or a counterclockwise direction by the driving portion, and the support rod SB can be moved by the gear portion GA.

[0185] When the gear portion GA rotates in the counterclockwise direction, the second housing CS2 can move in the first direction DR1, and the support plate SPP moves in the first direction DR1 according to the movement of the support rod SB. Figure 2 As shown in , the extended mode of the display device DD can be realized. On the contrary, when the gear portion GA is rotated in the clockwise direction by the driving portion, as shown in FIG. Figure 1 As shown in , the basic mode of the display device DD can be realized.

[0186] According to the rotation amount of the gear part GA, the movement amount of the second housing CS2 can be determined. Therefore, the extension area of ​​the display module DM can be determined according to the rotation amount of the gear part GA. The rotation amount of the gear part GA can be selectively adjusted by the user operating the driving part. However, the embodiments of the present inventive concept are not limited thereto, and the second housing CS2 can be moved by an external force from the user.

[0187] In the extension mode, a portion of the support bar SB may be moved along the curved portion CVP to be positioned in the portion of the first extension portion EX1. The sub-support portion SSP may be located below the support bar SB positioned in the portion of the first extension portion EX1. Therefore, in the extension mode, the support bar SB that has been moved to the first extension portion EX1 may be located on the sub-support portion SSP.

[0188] When the sub-support portion SSP is not located in the first case CS1, the support bar SB having moved to the first extension portion EX1 may droop and be changed by an external force between the first side wall SW1 and the second side wall SW2.

[0189] However, according to some example embodiments of the inventive concept, since the support bar SB that has moved to the first extension part EX1 is located on the sub-support part SSP in the extended mode of the display device DD, the sub-support part SSP can support the support bar SB that has moved to the first extension part EX1. Since the sub-support part SSP supports the support bar SB that has moved to the first extension part EX1, the change of the support bar SB due to external force can be prevented.

[0190] Therefore, the display device DD according to some example embodiments of the inventive concepts may prevent the supporting bar SB from being changed.

[0191] According to some example embodiments of the inventive concept, in an extended mode of a display device in which an exposed surface of a display module extends, the sub-support part is located under a support bar supporting the display module to support the support bar, and thus changes of the support bar caused by external force may be prevented.

[0192] Although aspects of some example embodiments of the present disclosure have been described, it should be understood that the present disclosure should not be limited to these example embodiments, but various changes and modifications may be made by a person of ordinary skill in the art within the spirit and scope of the present disclosure as claimed. In addition, the embodiments disclosed in the present disclosure are not intended to limit the technical spirit of the present disclosure, and the protection scope of the present disclosure should be interpreted based on the attached claims and their equivalents, and it should be understood that all technical spirits included in the scope equivalent to the attached claims are included in the protection scope of the inventive concept.
