[0059] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0060] Figure 1 is a perspective view of a display device according to an embodiment of the present invention. Figure 2 It is used to illustrate Figure 1 A diagram showing an extended mode of the display device is shown.

[0061] Reference Figure 1 The display device DD according to the embodiment of the present invention may include a display module DM and a housing CS for housing the display module DM. The display module DM may be exposed to the outside through an opening portion OP defined at an upper portion of the housing CS.

[0062] The housing CS may include a first housing CS1 and a second housing CS2 that are coupled to each other to accommodate the display module DM. The first housing CS1 may be coupled to the second housing CS2 in a manner of being movable in a first direction DR1.

[0063] Hereinafter, a direction intersecting the first direction DR1 is defined as a second direction DR2. A direction intersecting substantially perpendicularly with a plane defined by the first and second directions DR1 and DR2 is defined as a third direction DR3. In this specification, the meaning of "when viewed on a plane" may refer to a state viewed in the third direction DR3.

[0064] Reference Figure 1 as well as Figure 2 The first housing CS1 can move along the first direction DR1 in a direction away from or close to the second housing CS2. When the first housing CS1 moves in the first direction DR1, the area of ​​the exposed surface of the display module DM can be adjusted according to the movement of the first housing CS1.

[0065] The display module DM may be a flexible display module and may be supported by a support portion disposed below the display module DM. The detailed structure of the support portion will refer to the following Fig. 9 to explain in detail.

[0066] The display module DM and the support part can be accommodated in the first housing CS1 and the second housing CS2. The display module DM and the support part can be connected to the second housing CS2, and when the first housing CS1 moves from the second housing CS2 along the first direction DR1, the display module DM and the support part also move in the first direction DR1.

[0068] Reference Figure 2 , the first housing CS1 can move in the first direction DR1 in a manner away from the second housing CS2. The display module DM can move in the first direction DR1 according to the movement of the first housing CS1, and as a result, the exposed surface of the display module DM is expanded. The exposed surface of the display module DM is expanded, so that the user can recognize the image through a larger screen. The state of the display device DD in which the exposed surface of the display module DM is expanded can be defined as an extended mode.

[0069] Reference Figure 1 , the first housing CS1 can move in the first direction DR1 in a manner close to the second housing CS2. When the first housing CS1 moves to the maximum toward the second housing CS2, the exposed surface of the display module DM can be set to the minimum. Such a state of the display device DD can be defined as a basic mode. The basic mode and the extended mode of the display device DD can be realized according to the movement of the first housing CS1.

To prevent such a phenomenon, the anti-reflection layer RPL may include a plurality of color filters displaying the same color as the pixels of the display panel DP.

[0101] For example, the input sensing portion ISP may be directly formed on the display panel DP, and the anti-reflection layer RPL may be directly formed on the input sensing portion ISP, but the embodiments of the present invention are not limited thereto. For example, the input sensing portion ISP may be manufactured separately and attached to the display panel DP via an adhesive layer, and the anti-reflection layer RPL may be manufactured separately and also attached to the input sensing portion ISP via an adhesive layer.

[0137] Reference Fig. 9 as well as Fig.11 , the support rod SB can be connected to the support plate SPT. For example, according to the welding process, the support rod SB can be connected to the bottom of the soft part FLP of the support plate SPT.

[0138] The link rod LKB may be connected to both sides of the support rod SB opposite to each other in the second direction DR2. For example, according to a welding process, the link rod LKB may be connected to both sides of the support rod SB. The portion of the first extension portion EX1 disposed inside the second extension portion EX2 may be disposed under the soft portion FLP and connected to both sides of the support rod SB.
