Here, it is possible that the first short side area SS1 is referred to as a first side area, the second short side area SS2 is referred to as a second side area opposite the first side area, the first long side area LS1 is referred to as a third side area adjacent to the first side area and the second side area and positioned between the first side area and the second side area, and the second long side area LS2 is referred to as a fourth side area adjacent to the first side area and the second side area and positioned between the first side area and the second side area and opposite the third side area.

In addition, for convenience of description, although lengths of the first and second long sides LS1 and LS2 are longer than lengths of the first and second short sides SS1 and SS2, the lengths of the first and second long sides LS1 and LS2 may be approximately equal to the lengths of the first and second short sides SS1 and SS2.

In addition, hereinafter, a first direction X(DR1) may be a direction parallel to the long sides LS1 and LS2 of a display panel 110, and a second direction Y(DR2) may be a direction parallel to the short sides SS1 and SS2 of the display panel 110.

In another aspect, a side where the display panel 110 of the display device 1000 displays images may be referred to as a front side or a front surface. When the display panel 110 of the display device 1000 displays images, a side where the images cannot be observed may be referred to as a back side or a back surface. When looking at the display panel 110 of the display device 1000 from the front side or the front surface, the first long side LS1 may be referred to as an upper side or an upper surface. Similarly, the second long side LS2 may be referred to as a lower side or a lower surface. Similarly, the first short side SS1 may be referred to as a right side or a right surface, and the second short side SS2 may be referred to as a left side or a left surface.

The display panel 110 may be an organic light emitting diode (OLED) panel. An active matrix type organic light emitting display panel includes an organic light emitting diode (hereinafter referred to as “OLED”) that emits light by itself, and has advantages such as a fast response speed, high light emission efficiency, high brightness, and a wide viewing angle.

The OLED, which is a self-emission device, includes an anode electrode, a cathode electrode, and organic compound layers (HIL, HTL, EML, ETL, EIL) formed therebetween. The organic compound layer is formed of a hole injection layer (HIL), a hole transport layer (HTL), an emission layer (EML), an electron transport layer (ETL), and an electron injection layer (EIL). When a driving voltage is applied to the anode electrode and the cathode electrode, holes passing through the hole transport layer HTL and electrons passing through the electron transport layer ETL are moved to the emission layer EML to form excitons, and as a result, the emission layer EML generates visible light.

Accordingly, the OLED does not require a separate light source, and the volume and weight of the display device 1000 can be reduced. In addition, since the response speed of the OLED is 1000 times faster than that of the liquid crystal display device, an afterimage may not remain when displaying an image.

Referring to FIG. 9, sliding covers 311c and 312c may include a first sliding cover 311c and a second sliding cover 312c. The first sliding cover 311c may cover the upper part or upper surface of the upper mounting member 311. In addition, the second sliding cover 312c may cover the first upper roller housing 312 and the second upper roller housing 313.

The first sliding member 310 covers the upper mounting member 311 and the upper roller housings 312 and 313 using the first sliding cover 311c and the second sliding cover 312c, so that it is possible to prevent dust or foreign matter from entering the upper mounting member 311 and the upper roller housings 312 and 313.

Referring to FIGS. 10 to 12, the second sliding member 330 may include a lower mounting member 331, a lower roller 335 and a lower roller housing 333.

Since the second sliding member 330 and the third sliding member 350 have substantially the same configuration, the second sliding member 330 will be described with reference to FIGS. 10 to 12.

The lower mounting member 331 may be formed in a shape capable of having a width wider than that of the second frame 220. The lower mounting member 331 may face the lower surface or the bottom surface of the display module 100. An adhesive member (not shown) may fix the lower surface or the bottom surface of the display module 100 placed on the lower mounting member 331.

The second frame 220 may be disposed below the display module 100 or the lower mounting member 331.

In addition, the lower mounting member 331 may include a plurality of fastening holes h3 on an upper part. The plurality of fastening holes h3 may penetrate the upper part of the lower mounting member 331.

The lower roller housing 333 may be disposed on a lower part or a lower end of the lower mounting member 331. The second frame 220 may penetrate the lower roller housing 333 in the left-right direction X. The lower roller housing 333 may surround both sides of the second frame 220, and may be spaced apart from the second frame 220 at a predetermined interval.

The lower roller housing 333 may include a plurality of fastening grooves h4 on an upper part.

The fastening member 201 may penetrate the fastening hole h3 and be inserted into the fastening groove h4. The fastening member 201 may fix the lower mounting member 331 and the lower roller housing 333.

The plurality of fastening grooves h4 may be formed in a larger number than the fastening holes h3 disposed in the lower mounting member 331. Thus, the fastening groove h4 of the lower roller housing 333 is formed more than the fastening hole h3 of the lower mounting member 331, a length between the second sliding member 330 and the third sliding member 350 can be easily adjusted depending on the size of the display module 100. Accordingly, the second sliding member 330 and the third sliding member 350 can more stably sustain or support the display module 100.

The lower roller 335 may be disposed inside the lower roller housing 333. The lower roller 335 may be referred to as a lower sliding roller.

The lower roller 335 may be disposed between the lower mounting member 331 and the second frame 220. The lower roller 335 may face the lower mounting member 331 and may be in contact with an upper end or an upper part of the second frame 220.

Referring to FIGS. 13 to 15, the second frame 220 may be bent in a curved shape. The first partial frame 211 among the first frames 210 may be bent in a curved shape. The remaining second and third partial frames 212 and 213 except for the first partial frame 211 may be formed in a straight line.

The first partial frame 211 may have a first radius of curvature R1 from a center of curvature C. The center of curvature C may be a center of a circle having the first radius of curvature R1 as the length of the radius. The first radius of curvature R1 may be referred to as a first radius.

The second frame 220 may have a second radius of curvature R2 from the center of curvature C. The center of curvature C may be the center of a circle having the second radius of curvature R2 as the length of the radius. The second radius of curvature R2 may be referred to as a second radius.

The center of curvature C of the first partial frame 211 is the same as the center of curvature C of the second frame 220.

The upper rollers 315, 316, 317 and the lower roller 335 are disposed in a normal direction of the curvature based on the center of curvature C to easily implement a sliding operation.

Thus, the center of curvature C of the first partial frame 211 is disposed substantially to be the same as the center of curvature C of the second frame 220, the upper rollers 315, 316, 317 of the first sliding member 310 sliding on the first partial frame 211 and the lower roller 335 of the second and third sliding members 330 and 350 sliding on the second frame 220 may operate smoothly along the bent first and second frames 210 and 220.

Accordingly, since the display device 1000 can move the display module 100 mounted on the bent first frame 210 and the second frame 220 in a curved manner it may freely adjust a screen angle of the display panel 100 depending on the user's location.

If the center of curvature C of the first partial frame 211 is the same as the center of curvature C of the second frame 220, the first radius of curvature R1 may be less than the second radius of curvature R2. The second frame 220 may protrude more toward the front of the display module 100 than the first frame 210.

Referring to FIGS. 16 to 22, the first sliding member 310 may be attached to the back surface of the display module 100 and mounted on the frame 200. In addition, the display module 100 may be placed on the second sliding member 330 (see FIG. 13) and the third sliding member 350 (see FIG. 13) and mounted on the frame. In FIGS. 16 to 22, all of the first sliding member 310 to the third sliding member 350 are collectively referred to as the sliding member 310.

As shown in FIG. 16, the display module 100 may be basically disposed at the center of the frame 200.

If the viewer is located or standing on the right side of the frame 200 rather than the center of the frame 200, the display module 100 may naturally move the display module 100 mounted on the frame 200 to the left along the curved frame 200 along the sliding member 310. FIGS. 17 to 19 illustrate the display module 100 moved to the right at various angles.

On the other hand, if the viewer is located or standing on the left side of the frame 200 rather than the center of the frame 200, the display module 100 may naturally move the display module 100 mounted on the frame 200 to the left along the curved frame 200 along the sliding member 310. FIGS. 20 to 22 illustrate the display module 100 moved to the left at various angles.

Referring to FIG. 23, a first frame 211a may include a first upper frame 211a1, a second upper frame 211a2, and an upper groove 211a3.

The first upper frame 211a1 may be disposed around the upper part or upper side of the display module 100. The first upper frame 211a1 may be disposed to be long in the left-right direction X corresponding to the first long side LS1 (refer to FIG. 1) of the display module 100.

The second upper frame 211a2 may be disposed to be spaced apart from the first upper frame 211a1 in the vertical direction. The second upper frame 211a2 may be disposed around the upper part or upper side of the display module 100. The second upper frame 211a2 may be disposed to be long in the left-right direction X corresponding to the first long side LS1 (refer to FIG. 1) of the display module 100.

The upper groove 211a3 may be formed concavely between the first upper frame 211a1 and the second upper frame 211a2.

A fourth sliding member 310a may include an upper mounting member 311a, an upper roller 313a, and an upper roller housing 312a.

The upper mounting member 311 may be disposed to be long along the first long side LS1 (see FIG. 1) of the display module 100.

The upper roller housing 312a may protrude from the upper mounting member 311 to the back of the display module 100 and may be bent below the display module 100.

The upper roller housing 312a may be spaced apart from the upper part or upper side of the first upper frame 211a1.

The upper roller 313a may be disposed inside the upper roller housing 312a. One side of the upper roller 313a may be fastened to the inner side of the upper roller housing 312a.

The upper roller 313a may be inserted into the upper groove 211a3, face the first upper frame 211a1, and be in contact with the second upper frame 211a2.

Since the upper roller 313a is inserted into the upper groove 211a3, it is possible to prevent the display module 100 from falling down to the front F.
