When a flexible display device capable of folding is folded, components constituting the display device slip from each other, so that edges may not overlap or may be spaced apart from each other. Specifically, when a display device having a structure in which each component is stacked vertically is folded, the radius of curvature at which the uppermost component and the lowermost component are folded may be different. Therefore, when the display device is folded, the adhesive layer is stretched due to stress, and the edges of each component may be moved.

Meanwhile, in order to receive a user's touch input, a touch panel including a plurality of touch lines in a mesh shape is disposed on the display panel. In this case, a plurality of touch lines may be disposed between each of the plurality of light emitting devices to minimize interference between the light emitted from the light emitting device and the plurality of touch lines.

However, as described above, when the display device is folded, each component of the display device is folded with a different radius of curvature and the edge is moved, so that a plurality of light emitting elements and a plurality of touch lines may also be moved along the edge. . Accordingly, the inventors of the present invention believe that when the display device is folded, a plurality of light-emitting elements and a plurality of touch lines partially overlap, so that light emitted from the plurality of light-emitting elements may interfere with the plurality of touch lines, and color shift (color shift). The problem that the shift) phenomenon occurs was recognized.

Accordingly, the inventors of the present invention invented a display device having a new structure capable of improving a color shift phenomenon due to overlapping of a touch electrode and a light emitting element when the display device is folded.

Accordingly, an object to be solved by the present invention is to provide a display device capable of improving a color shift phenomenon that occurs when the display device is folded.

Another problem to be solved by the present invention is to provide a display device in which the overlapping of a touch line with a light emitting area is minimized when the display device is folded.

Are placed closer together. Accordingly, when the display device is folded, it is possible to minimize the overlapping of the moving touch line with the light emitting area, thereby improving the color shift phenomenon.

In the display device according to another exemplary embodiment of the present invention, it is possible to switch between a folded state that is folded based on a folding axis and a non-folded state that is a flat state, and a plurality of light emitting regions and a non-emitting region surrounding the plurality of light emitting regions are defined.

In addition, in the non-folding state, since the plurality of touch lines 131 are arranged to be skewed in the non-emission area NEA, the centers 131C of each of the plurality of openings 131O surrounded by the plurality of touch lines 131 are plural. It may not overlap with the center EAC of each of the light-emitting areas EA of.

Specifically, in the non-folding state, the center 131C of each of the plurality of openings 13130 is closer to the folding axis FX than the center EAC of the light emitting area EA corresponding to each of the plurality of openings 13130 Can be arranged in a way. For example, in the first non-folding area NFA1, the centers 131C of the plurality of openings 13130 may be disposed closer to the folding axis FX than the centers EAC of the corresponding plurality of light emitting areas EA. I can. In the second non-folding area NFA2, the centers 131C of the plurality of openings 1130 may be disposed closer to the folding axis FX than the centers EAC of the corresponding plurality of light emitting areas EA. In other words, in the non-folding state, each of the plurality of light emitting regions EA may be disposed in a direction away from the folding axis FX within the corresponding plurality of openings 13130.

In addition, in each of the first non-folding area NFA1 and the second non-folding area NFA2, the plurality of touch electrodes TE and the plurality of light emitting areas EA may be symmetrical to each other. For example, in the first non-folding area NFA1, the centers 131C of each of the plurality of openings 13310 are disposed adjacent to the folding axis FX than the centers EAC of the plurality of emission areas EA. In the second non-folding area NFA2, the centers 131C of each of the plurality of openings 13130 are disposed closer to the folding axis FX than the centers EAC of the plurality of light emitting areas EA.

Referring to FIG. 4 together, a first insulating layer 132 is disposed on the touch line 131. The first insulating layer 132 may insulate components disposed above and below the first insulating layer 132. For example, a touch line 131 of the touch electrode TE extending in the column direction among the plurality of touch electrodes TE is disposed under the first insulating layer 132, and A touch line 131 of the touch electrode TE extending in the row direction among the plurality of touch electrodes TE may be disposed on the upper part. Therefore, each of the plurality of touch electrodes TE extending in the column "??*" and in the row direction may be insulated by the first insulating layer 132. In addition, among the upper or lower portions of the first insulating layer 132 When all of the plurality of touch electrodes TE are formed in any one place, the first insulating layer 132 may be formed in a region where the touch electrode TE extending in the row direction and the touch electrode TE extending in the column direction overlap. Each of the touch electrodes TE may be connected through a contact hole and a bridge electrode.

Meanwhile, as shown in FIG. 2, when the display device 100 is in a flatly unfolded state, the edge of the cover window 110, the edge of the polarizing plate 120, the edge of the display panel 140, and the touch panel The edge of 130 and the edge of the back plate 150 may overlap. On the other hand, when the display device 100 is in the folded and folded state, the edge of the cover window 110, the edge of the polarizing plate 120, the edge of the display panel 140, the edge of the touch panel 130, and the back plate 150 The edges of the can be separated from each other.

Hereinafter, a folding state in which the display device 100 is in-folded will be described.

5 is a cross-sectional view of an in-folding display device according to an exemplary embodiment of the present invention. 6 is a plan view of a display device according to an exemplary embodiment of the present invention. 7 is a cross-sectional view taken along line VII-VII' of FIG. 6. In FIG. 6, a plan view of the display device 100 is illustrated for convenience of description, but it is assumed that the display device 100 is in-folded. In FIG. 6, when the display device 100 is in-folded, the touch line 131 and the light emitting area EA are enlarged and illustrated in the first non-folding area NFA1 and the second non-folding area NFA2.

Referring to FIG. 5, the display device 100 according to an exemplary embodiment may be in-folded. When the display device 100 is in-folded, it may be folded so that the touch panel 130 is disposed inside and the display panel 140 is disposed outside. In the in-folded display device 100, a back plate 150 is disposed on the outermost side, and a cover window 110 is disposed on the inner side, so that the first non-folding area NFA1 and the second non-folding area NFA2 are respectively One surface of the cover window 110 overlapping with each other may face each other.

When the display device 100 is folded, the components of the display device 100 slip from each other so that the edges of the components of the display device 100 do not overlap, but may be separated from each other. In addition, as the components of the display device 100 slip, stress generated during folding may be alleviated.

Specifically, when the display device 100 is in-folded, positions of edges of components of the display device 100 may be changed. When the display device 100 is folded, the radius of curvature at which each component is folded becomes different from each other. When folding, the radius of curvature of the component disposed on the outermost side is larger than the radius of curvature of the component disposed on the inside. And, in the case of a component having a relatively large radius of curvature, the degree of slip of the edge may increase. For example, when the display device 100 is in-folded, the edge of the touch panel 130 disposed inside the display panel 140 due to the stress applied by the folding becomes outward than the edge of the display panel 140. It can be slid. On the other hand, the edge of the back plate 150 disposed outside the display panel 140 may slide inward than the edge of the display panel 140.

Meanwhile, when the display device 100 is in-folding, the touch panel 130 may be disposed inside the display panel 140, and the edge of the touch panel 130 slides outward than the edge of the display panel 140. Can be. In addition, as the edge of the touch panel 130 is moved to the outside of the display panel 140, the touch line 131 may also be moved outside the display panel 140 and away from the folding axis FX.

6 and 7, each of the plurality of touch lines 131 in the non-folding area NFA is along an edge of the touch panel 130 moved toward the outside of the display panel 140, and the display panel 140 It may be moved in a direction toward the outside of and away from the folding axis FX. When the display device 100 is in a non-folding state, the plurality of touch lines 131 may be disposed at the first position X. On the other hand, when the display device 100 is in the folding state, the plurality of touch lines 131 may be moved in a direction away from the folding axis FX at the first position X and may be disposed at the second position X'. have. For example, referring to FIGS. 6 and 7, in the first non-folding area NFA1 on the left side of the folding axis FX, the plurality of touch lines 131 may be moved to the folding axis ( FX) and can move toward the left. Further, referring to FIG. 6, in the second non-folding area NFA2 on the right side of the folding axis FX, the plurality of touch lines 131 are in a direction away from the folding axis FX by the movement of the edge of the touch panel 130. Interest can be moved to the right.

In this case, the touch line 131 moved due to the folding of the display device 100 may be continuously disposed to overlap the non-emission area NEA, and may not cover the emission area EA. Specifically, in the non-folding state, the touch lines 131 are arranged to be biased toward the folding axis FX between the light emitting regions EA facing each other with the touch line 131 interposed therebetween. That is, the center 131C of each of the plurality of openings 13130 surrounded by the touch line 131 may be disposed adjacent to the folding axis FX rather than the center EAC of the corresponding light emitting area EA. In addition, when the display device 100 is in-folded, the edge of the touch panel 130 is moved to the outside of the display panel 140, and the touch line 131 is also moved away from the folding axis FX. It can be moved toward the outside of. In addition, since the center 131C of each of the plurality of openings 13130 surrounded by the touch line 131 is also moved away from the folding axis FX, the center 131C of each of the plurality of openings 13130 is a corresponding light emitting area ( EA) can be moved towards the center of the (EAC). Therefore, even if the display device 100 is folded, since the touch line 131 is arranged to be offset from the non-emissive area NEA in the non-folding state, even if the touch line 131 is moved, it may be moved within the non-emissive area NEA. And may not cover the light emitting area EA.

If, in the non-folding state, when the centers 131C of the plurality of openings 13110 and the centers EAC of the plurality of light emitting areas EA are arranged to match, in the folded state, the touch line 131 is ) Can be moved to cover it. That is, when the touch line 131 is disposed in the middle between the two light emitting areas EA, the distance from the touch line 131 to the light emitting area EA may be smaller than the moving distance of the touch line 131. In this case, when the display device 100 is folded, the touch line 131 may move from the non-emissive area NEA toward the light-emitting area EA to overlap the light-emitting area EA. In addition, when the touch line 131 overlaps the emission area EA, the touch line 131 may block light from the emission area EA, and a color shift phenomenon may occur. That is, when the display device 100 is folded, if the touch line 131 is not arranged in the middle of the light emitting area EA, the touch line 131 is more than the moving distance of the touch line 131 during folding. The distance between the light emitting area EA and the light emitting area EA may be shortened. Therefore, if the touch line 131 is not asymmetrically disposed between the light emitting areas EA, the touch line 131 may cover the light emitting area EA, resulting in a color shift phenomenon, and light from the light emitting area EA. It can be recognized by this different color of light.

In the display device 100 according to the exemplary embodiment of the present invention, a plurality of touch lines 131 are asymmetrically arranged in the non-emission area NEA, so that a plurality of touches that are moved when the display device 100 is in-folding. Interference between the line 131 and the plurality of light emitting regions EA may be minimized. When the display device 100 is in-folded, the edge of the touch panel 130 may move toward the outside of the edge of the display panel 140, and the touch line 131 may also move in a direction away from the folding axis FX. . In this case, the touch line 131 may be arranged to be skewed toward the folding axis FX in the non-emission area NEA. In addition, when the display device 100 is in-folded, even if the touch line 131 moves in a direction away from the folding axis FX, the touch line 131 is already inclined toward the folding axis FX in a non-folding state. , A margin for preventing interference between the touch line 131 and the light emitting area EA may be secured. Accordingly, in the display device 100 according to an exemplary embodiment, the touch line 131 and the light emitting area EA are asymmetrically arranged to minimize interference between the light emitting area EA and the touch line 131 , It is possible to reduce the color shift phenomenon.

8 is a plan view of a display device according to another exemplary embodiment of the present invention. 9 is a cross-sectional view taken along line IX-IX' of FIG. 8. Specifically, FIG. 8 is a plan view of the display device 800 when the display device 800 according to another exemplary embodiment is unfolded. 9 is a cross-sectional view of the display device 800 when the display device 800 according to another exemplary embodiment is unfolded. In the display device 800 of FIGS. 8 and 9, compared to the display device 100 of FIGS. 1 to 7, the display device 800 is out-folded and only the arrangement of the touch line 831 is different. Since the configuration is substantially the same, redundant description will be omitted.

Referring to FIGS. 8 and 9, a plurality of touch lines 831 disposed in a non-folding area NFA is one of two light emitting areas EA facing each other with a touch line 831 interposed therebetween. It is placed closer to (EA). For example, in the first non-folding area NFA1, the touch line 831 is located in the left light emitting area EA of the two light emitting areas EA facing each other in the row direction with the touch line 831 interposed therebetween. It can be arranged more contiguously. For example, in the second non-folding area NFA2, the touch line 831 is located in the right light emitting area EA of the two light emitting areas EA facing each other in the row direction with the touch line 831 interposed therebetween. It can be arranged more contiguously.

In the non-folding state, the shortest distance from the edge farthest from the folding axis FX to the touch line 831 among the plurality of edges of one light-emitting area EA is among the plurality of edges of one light-emitting area EA. It may be longer than the shortest distance from the edge closest to the folding axis FX to the touch line 831. In other words, the distance from one side of the opening 831O closest to the folding axis FX to the center of the light emitting area EA (EAC) is emitted from the other side of the opening 831O farthest from the folding axis FX. It may be shorter than the distance to the center of the area EAC. For example, referring to FIG. 8, among a plurality of edges of one light emitting area EA in the second non-folding area NFA2, an edge farthest from the folding axis FX is a point A, and the folding axis FX The edge closest to and may be point B. In this case, the shortest distance T3 from the point A to the touch line 831 may be longer than the shortest distance T4 from the point B to the touch line 831.

In the non-folding state, the centers EAC of the plurality of light emitting areas EA may be disposed closer to the folding axis FX than the centers 831C of the corresponding plurality of openings 831O. For example, in the first non-folding area NFA1, the centers 831C of each of the plurality of openings 831O are greater than the centers EAC of the light-emitting area EA corresponding to each of the plurality of openings 831O. FX) can be placed away from. In the second non-folding area NFA2, the center 831C of each of the plurality of openings 831O is greater than the centers EAC of the plurality of light emitting areas EA corresponding to each of the plurality of openings 831O. Can be placed away from In other words, in the case of the non-folding state, each of the plurality of light emitting regions EA may be disposed in a direction toward the folding axis FX within the corresponding plurality of openings 831O.

Hereinafter, a folding state in which the display device 800 is out-folded will be described.

10 is a cross-sectional view of an out-folding of a display device according to another exemplary embodiment of the present invention. 11 is a plan view of a display device according to another exemplary embodiment of the present invention. 12 is a cross-sectional view taken along line XII-XII' of FIG. 11. In FIG. 11, a plan view of the display device 800 is illustrated for convenience of description, but it is assumed that the display device 800 is out-folded. In FIG. 11, when the display device 800 is out-folded, the touch line 831 and the light emitting area EA are enlarged and illustrated in the first non-folding area NFA1 and the second non-folding area NFA2.

Referring to FIG. 10, a display device 800 according to another exemplary embodiment of the present invention may be out-folded. When the display device 800 is out-folded, the display panel 140 may be disposed inside and the touch panel 830 may be folded outside. In the out-folded display device 800, a cover window 110 is disposed on the outermost side, and a back plate 150 is disposed on the inner side, so that the first non-folding area NFA1 and the second non-folding area NFA2 are respectively One surface of the back plate 150 overlapping with each other may face each other.

When the display device 800 is out-folded, positions of edges of components of the display device 800 may be changed. When the display device 800 is folded, the radius of curvature at which each component is folded becomes different from each other. When folding, the radius of curvature of the component disposed on the outermost side is larger than the radius of curvature of the component disposed on the inside. And, in the case of a component having a relatively large radius of curvature, the degree of slip of the edge may be increased. For example, when the display device 800 is out-folded, the edge of the touch panel 830 disposed outside the display panel 140 due to the stress applied by the folding becomes inward than the edge of the display panel 140. It can be slid. On the other hand, the edge of the back plate 150 disposed inside the display panel 140 may slide outward than the edge of the display panel 140.

Meanwhile, when the display device 800 is out-folded, the touch panel 830 may be disposed outside the display panel 140, and the edge of the touch panel 830 is inside the edge of the display panel 140. It can be slid. In addition, as the edge of the touch panel 830 is moved to the inside of the display panel 140, the touch line 831 may also be moved inside the display panel 140 and in a direction closer to the folding axis FX.

Referring to FIGS. 11 and 12 together, each of the plurality of touch lines 831 in the non-folding area NFA follows an edge of the touch panel 830 moved toward the inside of the display panel 140. ) And may be moved in a direction closer to the folding axis FX. When the display device 800 is in a non-folding state, the plurality of touch lines 831 may be disposed at the first position X. On the other hand, when the display device 800 is in the folding state, the plurality of touch lines 831 move in a direction closer to the folding axis FX at the first position X and are disposed at the second position X'. I can. For example, in the first non-folding area NFA1 on the left side of the folding axis FX, the plurality of touch lines 831 are in a direction closer to the folding axis FX due to the movement of the edge of the touch panel 830 and the right side. Can move towards. For example, in the second non-folding area NFA2 on the right side of the folding axis FX, the plurality of touch lines 831 are in a direction closer to the folding axis FX due to the movement of the edge of the touch panel 830 and the left side. Can move towards.

In this case, the touch line 831 moved due to the folding of the display device 800 may be continuously disposed to overlap the non-emission area NEA, and may not cover the emission area EA. In the non-folding state, the touch lines 831 are arranged in a direction away from the folding axis FX between the light emitting regions EA facing each other with the touch line 831 interposed therebetween. The centers 831C of each of the plurality of openings 831O surrounded by the touch line 831 may be disposed farther from the folding axis FX than the center EAC of the corresponding light emitting area EA. In addition, when the display device 800 is out-folded, the edge of the touch panel 830 may be moved to the inside of the display panel 140, and the touch line 831 may also be moved to be close to the folding axis FX. Since the center 831C of each of the plurality of openings 831O surrounded by the touch line 831 is also moved to be close to the folding axis FX, the center 831C of each of the plurality of openings 831O is a corresponding light emitting area EA ) Can be moved toward the center of (EAC). Therefore, even if the display device 800 is folded, the touch line 831 arranged to be offset from the non-emissive area NEA in the non-folding state is moved, so that the touch line 831 can only be moved within the non-emissive area NEA. In addition, the light emitting area EA may not be covered.

Accordingly, in the display device 800 according to another exemplary embodiment of the present invention, a plurality of touch lines 831 are asymmetrically arranged in the non-emission area NEA, so that the plurality of touch lines 831 are moved when the display device 800 is out-folded. It is possible to minimize interference between the touch line 831 and the emission area EA of each other. When the display device 800 is out-folded, the edge of the touch panel 830 is moved toward the inside of the edge of the display panel 140, and the touch line 831 is also moved in a direction closer to the folding axis FX. I can. In this case, the touch line 831 may be arranged in a direction away from the folding axis FX in the non-emission area NEA. In addition, when the display device 800 is out-folded, even if the touch line 831 is moved in a direction closer to the folding axis FX, the touch line 831 is skewed in a direction away from the folding axis FX in a non-folding state. Since they are arranged, a margin for preventing interference between the touch line 831 and the light emitting area EA can be secured. Accordingly, when the display device 800 is out-folded, even if the touch line 831 is moved, it may be moved only within the non-emission area NEA and may not overlap the light emitting area EA. Accordingly, in the display device 800 according to another exemplary embodiment of the present invention, when the touch line 831 is folded in the non-emission area NEA, the touch line 831 is arranged to be skewed toward the direction opposite to the moving direction of the touch line 831.
