     Furthermore, embodiments of the present disclosure can provide a function of sensing a touch of a user on the display panel  110  by implementing a touch sensor structure on the display panel  110  displaying an image. 
       FIGS.  3  to  5    are diagrams illustrating examples of a touch sensor structure included in the touch display device  100  according to embodiments of the present disclosure. 
     Referring to  FIG.  3   , the touch display device  100  can include a plurality of touch electrode lines TEL and a plurality of touch routing lines TL disposed in the display panel  110 . The touch display device  100  can include a touch driving circuit  150  driving the plurality of touch electrode lines TEL and the plurality of touch routing lines TL. 
     Each of the plurality of touch electrode lines TEL can be electrically connected to the touch driving circuit  150  through the touch routing line TL. The touch driving circuit  150  can be disposed separately, in some cases, can be disposed to be integrated with a circuit for the display driving. For example, the touch driving circuit  150  can be disposed in a shape integrated with the data driving circuit  130 . 
     Each of the plurality of touch electrode lines TEL can include a plurality of touch electrodes TE electrically connected to each other along one direction. Furthermore, each of the plurality of touch electrode lines TEL can include a plurality of touch electrode connecting patterns CL electrically connecting the plurality of touch electrodes TE each other. 
     For example, each of a plurality of X-touch electrode lines X-TEL can include a plurality of X-touch electrodes X-TE arranged in a first direction and a plurality of X-touch electrode connecting patterns X-CL electrically connecting the plurality of X-touch electrodes X-TE each other. 
     Each of a plurality of Y-touch electrode lines Y-TEL can include a plurality of Y-touch electrodes Y-TE arranged in a second direction crossing the first direction and a plurality of Y-touch electrode connecting patterns Y-CL electrically connecting the plurality of Y-touch electrodes Y-TE each other. 
     The X-touch electrode line X-TEL and the Y-touch electrode line Y-TEL can be disposed on different layers from each other. Alternatively, the X-touch electrode X-TE and the Y-touch electrode Y-TE can be disposed on a same layer. In this case, one of the X-touch electrode connecting pattern X-CL and the Y-touch electrode connecting pattern Y-CL can be disposed on a different layer from the touch electrode TE. 
     The touch electrode TE, for example, can be a tetragonal shape, but not limited to this. 
     The touch electrode TE can be made of a transparent conductive material, and can be disposed without interrupting an image display function of the display panel  110 . 
     Alternatively, the touch electrode TE can be made of an opaque metal. In this case, the touch electrode TE can a shape that an area corresponding to a light-emitting area of the light-emitting element ED disposed in the display panel  110  is opened. For example, the touch electrode TE is implemented as a mesh type and disposed to avoid the light-emitting area. 
     In a structure that the plurality of X-touch electrode lines X-TEL and the plurality of Y-touch electrode lines Y-TEL are disposed to cross each other, the touch driving circuit  150  can drive the touch electrode line TEL through the touch routing line TL and perform the touch sensing. 
     For example, one of the X-touch electrode line X-TEL and the Y-touch electrode line Y-TEL can be a touch driving electrode which a touch driving signal is applied. The other one of the X-touch electrode line X-TEL and the Y-touch electrode line Y-TEL can be a touch sensing electrode which a touch sensing signal is detected. 
     The touch driving circuit  150  can detect a change of a mutual-capacitance generated when a user touches in a state that different signals are applied to the X-touch electrode line X-TEL and the Y-touch electrode line Y-TEL. 
     The touch driving circuit  150  can transmit a sensing data according to the change of the mutual-capacitance detected to a touch controller. The touch controller can detect whether a touch is occurred or not and a touch coordinate on the display panel  110  based on the sensing data received from the touch driving circuit  150 . 
     The touch electrode line TEL disposed in the display panel  110  can be disposed to be divided on a plurality of areas in the active area AA. 
     As the touch electrode line TEL is disposed to be divided on each area, a load of the touch electrode line TEL can be reduced. In the case that an area of the display panel  110  increases, the load of the touch electrode line TEL can be reduced and a performance of the touch sensing can be improved. 
     Referring to  FIG.  4   , the active area AA of the display panel  110  can include a plurality of sub-areas SAA divided by a boundary along the first direction and a boundary along the second direction. 
     The active area AA can include at least two or more sub-areas SAA divided by a first boundary BL 1  along the first direction. The active area AA can include at least two or more sub-areas SAA divided by a second boundary BL 2  along the second direction. 
     For example, a first sub-area SAA 1  and a second sub-area SAA 2  can be divided e.g., separated) by the first boundary BL 1 . A third sub-area SAA 3  and the fourth sub-area SAA can be divided (e.g., separated) by the first boundary BL 1 . 
     The first sub-area SAA 1  and the third sub-area SAA 3  can be divided (e.g., separated) by the second boundary BL 2 . The second sub-area SAA 2  and the fourth sub-area SAA 4  can be divided (e.g., separated) by the second boundary BL 2 . 
       FIG.  4    illustrates an example that the active area AA is divided as four sub-areas SAA, but the active area AA can be divided into a plurality of sub-areas SAA by the first boundary BL 1  and the second boundary BL 2 . 
     The touch electrode line TEL disposed on each of the plurality of sub-areas SAA can be disposed to be separated from the touch electrode line TEL disposed on a different sub-area SAA. 
     The touch electrode line TEL disposed on each of the plurality of sub-areas SAA can be driven independently from each other. 
     For example, a first X-touch electrode line X-TEL- 1  disposed on the first sub-area SAA 1  can be electrically connected to a first touch driving circuit  151  through a first X-touch routing line X-TL- 1 . A first Y-touch electrode line Y-TEL- 1  can be electrically connected to the first touch driving circuit  151  through a first Y-touch routing line Y-TL- 1 . 
     A second X-touch electrode line X-TEL- 2  disposed on the second sub-area SAA 2  can be electrically connected to a second touch driving circuit  152  through a second X-touch routing line X-TL- 2 . A second Y-touch electrode line Y-TEL- 2  can be electrically connected to the second touch driving circuit  152  through a second Y-touch routing line Y-TL- 2 . 
     The first X-touch electrode line X-TEL- 1  and the first Y-touch electrode line Y-TEL- 1  can be driven by the first touch driving circuit  151 . The second X-touch electrode line X-TEL- 2  and the second Y-touch electrode line Y-TEL- 2  can be driven by the second touch driving circuit  152 . The touch electrode line TEL of the third sub-area SAA 3  and the fourth sub-area SAA 4  can be disposed as a structure similar to the touch electrode line TEL disposed on the first sub-area SAA 1  and the second sub-area SAA 2 , and can be driven as a similar manner. 
     The touch electrode line TEL disposed on the first sub-area SAA 1  and the touch electrode line TEL disposed on the second sub-area SAA 2  are electrically divided and driven by different touch driving circuits  151  and  152   150 , the load for the touch sensing can be reduced and the performance of the touch sensing can be improved. 
     Furthermore, in some cases, the touch electrode lines TEL disposed on two or more sub-areas SAA can be driven by a same touch driving circuit  150 . For example, the touch electrode line TEL disposed on the first sub-area SAA 1  and the touch electrode line TEL disposed on the second sub-area SAA 2  can be driven by the same touch driving circuit  150 . The touch electrode line TEL disposed on the third sub-area SAA 3  and the touch electrode line TEL disposed on the fourth sub-area SAA 4  can be driven by the same touch driving circuit  150  that is different from the touch driving circuit that drives the touch electrode lines TEL in the first sub-area SAA 1  and the second sub-area SAA 2 . Alternatively, for another example, the touch electrode line TEL disposed on the first sub-area SAA 1 , the second sub-area SAA 2 , the third sub-area SAA 3  and the fourth sub-area SAA 4  can be driven by the same touch driving circuit  150 . In this case, as the touch electrode line TEL disposed on each sub-area SAA is disposed as a separated structure, the load of the touch electrode line TEL can be reduced and the performance of the touch sensing can be improved. 
     Such as described above, in a structure that the touch electrode line TEL is disposed separately on each of the plurality of sub-areas SAA, some of the touch routing lines TL can be disposed on the active area AA. 
     For example, the first X-touch routing line X-TL- 1  electrically connected to the first X-touch electrode line X-TEL- 1  of the first sub-area SAA 1  and the second X-touch routing line X-TL- 2  electrically connected to the second X-touch electrode line X-TEL- 2  of the second sub-area SAA 2  can be disposed on the non-active area NA. 
     The second Y-touch routing line Y-TL- 2  electrically connected to the second Y-touch electrode line Y-TEL- 2  of the second sub-area SAA 2  can be disposed on the non-active area NA. 
     In contrast, a part of the first Y-touch routing line Y-TL- 1  electrically connected to the first Y-touch electrode line Y-TEL- 1  of the first sub-area SAA 1  can be disposed on the active area AA and another part of the first Y-touch routing line Y-TL- 1  is disposed in the non-active area NA. 
     The part of the first Y-touch routing line Y-TL- 1  that is disposed in the active area AA can also be disposed on the second sub-area SAA 2 . The first Y-touch routing line Y-TL- 1  can pass the second sub-area SAA 2  and can be electrically connected to the first Y-touch electrode line Y-TEL- 1  disposed on the first sub-area SAA 1 . 
     As the part of the first Y-touch routing line Y-TL- 1  is disposed on the second sub-area SAA 2 , at least one of the second X-touch electrode line X-TEL- 2  or the second Y-touch electrode line Y-TEL- 2  disposed on the second sub-area SAA 2  can be disposed to be separated on an area where the first Y-touch routing line Y-TL- 1  is disposed.  FIG.  4    illustrates an example that the second Y-touch electrode line Y-TEL- 2  is disposed to be divided on the second sub-area SAA 2  due to an arrangement of the first Y-touch routing line Y-TL- 1 . As shown in  FIG.  4   , each first Y-touch routing line Y-TL- 1  is disposed between a pair of second Y-touch electrode lines Y-TEL 2 . 
     Such as described above, in the case that the touch electrode lines TEL are disposed to be divided on each sub-area SAA, the number of the touch routing line TL connected to the touch electrode line TEL can increase. As the number of the touch routing line TL increases, the non-active area NA can increase due to an arrangement of the touch routing line TL. But as the first Y-touch routing line Y-TL- 1  is electrically connected to the first Y-touch electrode line Y-TEL- 1  of the first sub-area SAA 1  through the active area AA, it may not be required that a separate area is added for an arrangement of the first Y-touch routing line Y-TL- 1  on the non-active area NA. Without increasing the non-active area NA due to an addition of the first Y-touch routing line Y-TL- 1 , the touch sensor structure divided as sub-area SAA can be implemented. 
     The touch sensor structure divided as the plurality of sub-areas SAA can be divided as an upper side touch sensor portion (e.g., a first portion) and a lower side touch sensor portion (e.g., a second portion) based on the first boundary BL 1 . Furthermore, the touch sensor structure can be divided as a left side touch sensor portion (e.g., a third portion) and a right side touch sensor portion (e.g., a fourth portion) based on the second boundary BL 2 . Here, the lower side touch sensor portion can be positioned closer to a pad that the touch routing line TL is connected to than the upper side touch sensor portion. That is, a distance between the lower touch sensor portion and an area where the pad that the touch routing line TL is connected is disposed can be less than a distance between the upper side touch sensor portion and the area where the pad is disposed. 
     Furthermore, as an area of the second Y-touch electrode line Y-TEL- 2  is reduced (e.g., smaller) compared to an area of the first Y-touch routing line Y-TL- 1 , a sensitivity difference of the touch sensing can be prevented or at least reduced by making an area of the first Y-touch electrode line Y-TEL- 1  identical or similar to an area of the second Y-touch electrode line Y-TEL- 2 . 
     Referring to  FIG.  5   , at least one first dummy electrode DME 1  separated from the first Y-touch electrode line Y-TEL- 1  can be disposed on at least a part of an area of the first sub-area SAA 1  corresponding to an area where the first Y-touch routing line Y-TL- 1  is disposed on the second sub-area SAA 2 . 
     The first dummy electrode DME 1  can be electrically separated from the first Y-touch electrode line Y-TEL- 1 . 
     A width of an area where the first dummy electrode DME 1  is disposed can be identical or similar to a width of the first Y-touch routing line Y-TL- 1 . Alternatively, the width of the area where the first dummy electrode DME 1  is disposed can be identical or similar to a width of an area where the second Y-touch electrode line Y-TEL- 2  is not disposed on the second sub-area SAA 2 . Furthermore, a space between two parts of the first Y-touch electrode line Y-TEL- 1  disposed on both sides of the first dummy electrode DME 1  can be identical or similar to a space between two parts of the second Y-touch electrode line Y-TEL- 2  disposed on both sides of the first Y-touch routing line Y-TL- 1 . 
     An area of the first Y-touch electrode line Y-TEL- 1  disposed on the first sub-area SAA 1  can be substantially identical to an area of the second Y-touch electrode line Y-TEL- 2  disposed on the second sub-area SAA 2 . 
     Even the first Y-touch routing line Y-TL- 1  is disposed to pass the first sub-area SAA 1 , it can be prevented that a difference between touch sensitivity by the first Y-touch electrode line Y-TEL- 1  of the first sub-area SAA 1  and touch sensitivity by the second Y-touch electrode line Y-TEL- 2  of the second sub-area SAA 2  is generated, or the difference can be reduced. 
     According to embodiments of the present disclosure, as the active area AA is divided as the plurality of sub-areas SAA, and the touch is sensed by disposing the touch electrode line TEL on each of the plurality of sub-areas SAA, thus the load of the touch electrode line TEL can be reduced and the performance of the touch sensing can be improved even an area of the active area AA increases. 
     Furthermore, by making an area of the touch electrode line TEL disposed on each sub-area SAA to be identical or similar to each other, thus it can be prevented that the difference of touch sensitivity by the touch electrode line TEL disposed on each sub-area SAA is generated. 
     Each of the plurality of touch electrode TE included in the touch electrode line TEL, such as an example above-mentioned, can be a tetragonal shape, but can have various structures for improving the performance of the touch sensing. 
       FIG.  6    is a diagram illustrating an example of a structure of the touch electrode TE included in the touch sensor structure of the touch display device  100  according to an embodiment of the present disclosure. 
     Referring to  FIG.  6   , it illustrates examples of shapes of the X-touch electrode X-TE included in the X-touch electrode line X-TEL and the Y-touch electrode Y-TE included in the Y-touch electrode line Y-TEL.  FIG.  6    is a diagram for describing an example of a structure of the touch electrode TE, it exemplary illustrates a case that the X-touch electrode line X-TEL and the Y-touch electrode line Y-TEL are crossing each other and the X-touch electrode X-TE and the Y-touch electrode Y-TE are disposed on a same layer. 
     The X-touch electrode X-TE can have a similar shape to the Y-touch electrode Y-TE. 
     Describing a shape of the touch electrode X-TE using the X-touch electrode X-TE as an example, the X-touch electrode X-TE can include at least a body portion X-TE-a and a plurality of wing portions X-TE-b. 
     The body portion X-TE-a of the X-touch electrode X-TE can be disposed in the first direction or the second direction,  FIG.  6    illustrates an example that the body portion X-TE-a of the X-touch electrode X-TE is disposed in the second direction. 
     The wing portion X-TE-b of the X-touch electrode X-TE can be disposed in a direction crossing the body portion X-TE-a,  FIG.  6    illustrates an example that the wing portion X-TE-b of the X-touch electrode X-TE is disposed in the first direction. 
     A width of the body portion X-TE-a of the X-touch electrode X-TE can be identical to a width of the wing portion X-TE-b of the X-touch electrode X-TE. Alternatively, the width of the body portion X-TE-a of the X-touch electrode X-TE can be greater than the width of the wing portion X-TE-b of the X-touch electrode X-TE. 
     The body portion X-TE-a of the X-touch electrode X-TE can be disposed to be alternated with a body portion Y-TE-a of the Y-touch electrode Y-TE in the first direction with a wing portion X-TE-b or a wing portion Y-TE-b disposed between the body portion X-TE-a and the body portion Y-TE-a. 
     The wing portion X-TE-b of the X-touch electrode X-TE can be disposed to be alternated with a wing portion Y-TE-b of the Y-touch electrode Y-TE in the second direction. 
     The wing portion X-TE-b of the X-touch electrode X-TE and the wing portion Y-TE-b of the Y-touch electrode Y-TE can be disposed to be interlocked each other. An area that an outer line of the X-touch electrode X-TE and an outer line of the Y-touch electrode Y-TE are faced to each other can increase. Furthermore, a length of a boundary between the X-touch electrode X-TE and the Y-touch electrode Y-TE can increase. The performance of the touch sensing based on the change of the mutual-capacitance between the X-touch electrode X-TE and the Y-touch electrode Y-TE can be improved. 
     The X-touch electrode X-TE and the Y-touch electrode Y-TE can be disposed by using an electrode disposed on a same layer. One of the X-touch electrode X-TE and the Y-touch electrode Y-TE can be connected by an electrode disposed on a same layer as the touch electrode TE, and the other can be connected by an electrode disposed on a different layer from the touch electrode TE. 
     For example, the Y-touch electrode Y-TE connected in the second direction can be connected by an electrode disposed on a same layer as the touch electrode TE. 
     The X-touch electrodes X-TE connected in the first direction can be electrically connected by the X-touch electrode connecting pattern X-CL disposed on a different layer from the X-touch electrodes X-TE. 
     For example, the X-touch electrode X-TE and the Y-touch electrode Y-TE can be disposed by using a first touch sensor metal TSM 1 . The X-touch electrode connecting pattern X-CL can be disposed by using a second touch sensor metal TSM 2 . 
     The second touch sensor metal TSM 2  can be disposed on a different layer from the first touch sensor metal TSM 1 . 
     The X-touch electrode X-TE and the X-touch electrode connecting pattern X-CL can be electrically connected to each other through a contact hole CH. 
     Such as described above, the touch electrode line TEL can be implemented by using a layer where the first touch sensor metal TSM 1  is disposed and a layer where the second touch sensor metal TSM 2  is disposed. 
     By a structure that the touch electrode TE includes the body portion TE-a and the wing portion TE-b, a boundary between the X-touch electrode X-TE and the Y-touch electrode Y-TE can be increased and sensitivity of the touch sensing can be improved. 
     Furthermore, by a structure of the touch electrode line TEL disposed separately on each sub-area SAA of the active area AA, the load can be reduced and the performance of the touch sensing can be improved. 
       FIG.  7    is a diagram illustrating an example that the touch sensor structure illustrated in  FIG.  5    is implemented by the structure of the touch electrode TE illustrated in  FIG.  6    according to an embodiment.  FIG.  7    exemplary illustrates a touch sensor structure implemented on an area indicated by  501  illustrated in  FIG.  5   . 
     Referring to  FIGS.  6  and  7   , the active area AA, for example, can be divided as four sub-areas SAA 1 , SAA 2 , SAA 3 , SAA 4  by the first boundary BL 1  and the second boundary BL 2 . The touch electrode line TEL disposed on each of four sub-areas SAA 1 , SAA 2 , SAA 3 , SAA 4  can be disposed to be divided from each other. 
     The touch electrode line TEL disposed on each sub-area SAA can include the plurality of X-touch electrode lines X-TEL and the plurality of Y-touch electrode lines Y-TEL. 
     Each of the plurality of X-touch electrode lines X-TEL can include the plurality of X-touch electrodes X-TE. Each of the plurality of Y-touch electrode lines Y-TEL can include the plurality of Y-touch electrodes Y-TE. The X-touch electrode X-TE and the Y-touch electrode Y-TE can constitute one sensing unit SU. 
     The plurality of X-touch electrodes X-TE included in the X-touch electrode line X-TEL can be electrically connected by the X-touch electrode connecting pattern X-CL. 
     For example, the plurality of X-touch electrode X-TE can be made of the first touch sensor metal TSM 1 . The X-touch electrode connecting pattern X-CL can be made of the second touch sensor metal TSM 2  disposed on a layer different from a layer where the first touch sensor metal TSM 1  is disposed. 
     The X-touch electrode connecting pattern X-CL can be disposed in the first direction and can be electrically connected to the X-touch electrode X-TE through the contact hole CH. The plurality of X-touch electrode X-TE can be electrically connected in the first direction and can constitute the X-touch electrode line X-TEL. 
     The X-touch electrode connecting pattern X-CL, for example, can be disposed on an area overlapping the wing portion X-TE-b of the X-touch electrode X-TE. The X-touch electrode connecting pattern X-CL may not be disposed on an area overlapping the wing portion Y-TE-b of the Y-touch electrode Y-TE. A part of the X-touch electrode connecting pattern X-CL can overlap the body portion Y-TE-a of the Y-touch electrode Y-TE. 
     A width Wa 1  of the wing portion X-TE-b of the X-touch electrode X-TE positioned on an area overlapping the X-touch electrode connecting pattern X-CL can be greater than a width Wa 2  of the wing portion X-TE-b of the X-touch electrode X-TE positioned on an area not overlapping the X-touch electrode connecting pattern X-CL. 
     The width Wa 1  of the wing portion X-TE-b of the X-touch electrode positioned on an area overlapping the X-touch electrode connecting pattern X-CL can be greater than a width Wa 3  of the wing portion Y-TE-b of the Y-touch electrode Y-TE. 
     As the X-touch electrode connecting pattern X-CL is disposed to overlap the wing portion X-TE-b having a large width among the wing portion X-TE-b of the X-touch electrode X-TE, a width of the X-touch electrode connecting pattern X-CL or the number of the X-touch electrode connecting pattern X-CL can increase. The X-touch electrode X-TE can be electrically connected while reducing a resistance of the X-touch electrode connecting pattern X-CL. 
     On an area where the X-touch electrode connecting pattern X-CL is not disposed, as a width of the wing portion X-TE-b of the X-touch electrode X-TE and a width of the wing portion Y-TE-b of the Y-touch electrode Y-TE are small relatively, a structure that a boundary between the X-touch electrode X-TE and the Y-touch electrode Y-TE increases can be maintained and the performance of the touch sensing can be improved. 
     The X-touch electrode line X-TEL can be electrically connected to an X-touch electrode contact pad X-CP on a boundary of the active area AA and the non-active area NA. 
     For example, the X-touch electrode X-TE made of the first touch sensor metal TSM 1  can be disposed to be extended to the non-active area NA. The X-touch electrode contact pad X-CP made of the second touch sensor metal TSM 2  can be disposed on an area overlapping the extended X-touch electrode X-TE. The extended X-touch electrode X-TE and the X-touch electrode contact pad X-CP can be electrically connected through the contact hole CH. 
     Alternatively, the extended portion of the X-touch electrode X-TE disposed on the non-active area NA and the X-touch electrode contact pad X-CP made of the second touch sensor metal TSM 2  can be seen as the X-touch electrode contact pad X-CP integrally. 
     The X-touch electrode contact pad X-CP can be electrically connected to the X-touch routing line X-TL on the non-active area NA. The X-touch electrode line X-TEL can be electrically connected to the X-touch routing line X-TL through the X-touch electrode contact pad X-CP. The X-touch routing line X-TL can be made of at least one of the first touch sensor metal TSM 1  or the second touch sensor metal TSM 2 . 
     The plurality of Y-touch electrodes Y-TE included in the Y-touch electrode line Y-TEL can be directly connected to each other. 
     For example, the plurality of Y-touch electrodes Y-TE can be made of the first touch sensor metal TSM 1 . The plurality of Y-touch electrodes Y-TE can be connected in the second direction and can constitute the Y-touch electrode line Y-TEL. 
     The Y-touch electrode line Y-TEL disposed on the second sub-area SAA 2  and the fourth sub-area SAA 4  among the plurality of Y-touch electrode lines Y-TEL can be electrically connected to the Y-touch routing line Y-TL disposed on the non-active area NA on the boundary of the active area AA and the non-active area NA. 
     For example, the second Y-touch electrode line Y-TEL- 2  can be electrically connected to the second Y-touch routing line Y-TL- 2  on the boundary of the active area AA and the non-active area NA. The second Y-touch routing line Y-TL- 2  can be made of at least one of the first touch sensor metal TSM 1  or the second touch sensor metal TSM 2 . 
     The Y-touch electrode line Y-TEL disposed on the first sub-area SAA 1  and the third sub-area SAA 3  among the plurality of Y-touch electrode lines Y-TEL can be electrically connected to the Y-touch routing line Y-TL on the active area AA. 
     For example, the first Y-touch electrode line Y-TEL- 1  can be electrically connected to the first Y-touch routing line Y-TL- 1  on the active area AA. 
     The first Y-touch routing line Y-TL- 1  can be disposed on the non-active area NA and the second sub-area SAA 2 . The first Y-touch routing line Y-TL- 1  can pass the second sub-area SAA 2  and can be electrically connected to the first Y-touch electrode line Y-TEL- 1  disposed on the first sub-area SAA 1 . 
     The first Y-touch routing line Y-TL- 1 , for example, can be made of the first touch sensor metal TSM 1 . In some cases, the second touch sensor metal TSM 2  can be disposed on an area overlapping the first Y-touch routing line Y-TL- 1  and can be electrically connected to the first Y-touch routing line Y-TL- 1  through the contact hole CH, and can reduce a resistance of the first Y-touch routing line Y-TL- 1 . 
     As the first Y-touch routing line Y-TL- 1  is disposed on the second sub-area SAA 2 , the second Y-touch electrode line Y-TEL- 2  disposed on the second sub-area SAA 2  can be divided and disposed on both sides of the first Y-touch routing line Y-TL- 1 . 
     Two parts of the second Y-touch electrode line Y-TEL- 2  can be electrically connected to each other by being connected to the second Y-touch routing line Y-TL- 2  on the boundary of the active area AA and the non-active area NA. 
     Furthermore, the two parts of the second Y-touch electrode line Y-TEL- 2  can be electrically connected to each other by a second Y-touch electrode connecting pattern Y-CL- 2  disposed on the active area AA. 
     The second Y-touch electrode connecting pattern Y-CL- 2 , for example, can be made of the second touch sensor metal TSM 2 . 
     The two parts of the second Y-touch electrode line Y-TEL- 2  can be electrically connected to each other by at least one second Y-touch electrode connecting pattern Y-CL- 2 . For example, the second Y-touch electrode connecting pattern Y-CL- 2  can be disposed on an area adjacent to an upper boundary of the sensing unit SU and an area adjacent to a lower boundary of the sensing unit SU, and can be electrically connected to the second Y-touch electrode line Y-TEL- 2 . 
     As the two parts of the second Y-touch electrode line Y-TEL- 2  disposed to be separated from each other are connected on a plurality of points by the second Y-touch electrode connecting pattern Y-CL- 2 , it can be prevented that the load increases by a structure that the second Y-touch electrode line Y-TEL- 2  is divided. 
     The first Y-touch routing line Y-TL- 1  can pass the second sub-area SAA 2  and can be electrically connected to the first Y-touch electrode line Y-TEL- 1  on the first sub-area SAA 1 . 
     As the first Y-touch routing line Y-TL- 1  passes the second sub-area SAA 2  and is extended to the first sub-area SAA 1 , a portion of the first Y-touch routing line Y-TL- 1  can be disposed on the first boundary BL 1 . 
     A point that the first Y-touch routing line Y-TL- 1  is connected to the first Y-touch electrode line Y-TEL- 1  can be positioned inside of the first sub-area SAA 1 . The point that the first Y-touch routing line Y-TL- 1  is connected to the first Y-touch electrode line Y-TEL- 1  may not be positioned on the boundary of the first sub-area SAA 1  and the second sub-area SAA 2 . 
     As the first Y-touch routing line Y-TL- 1  passes the second sub-area SAA 2  and is electrically connected to the first Y-touch electrode line Y-TEL- 1  disposed on the first sub-area SAA 1 , in a structure that the touch electrode line TEL is divided and disposed on the plurality of sub-areas SAA, the touch routing line TL can be disposed without increasing the non-active area NA. 
     Since an area of the second Y-touch electrode line Y-TEL- 2  decreases according to that the first Y-touch routing line Y-TL- 1  is disposed on the second sub-area SAA 2 , an area of the first Y-touch electrode line Y-TEL- 1  positioned on an area corresponding to the second Y-touch electrode line Y-TEL- 2  can be identical or similar to an area of the second Y-touch electrode line Y-TEL- 2 . 
     For example, the first Y-touch electrode line Y-TEL- 1  can be disposed to be divided as two parts similar to the second Y-touch electrode line Y-TEL- 2 . 
     The two parts of the first Y-touch electrode line Y-TEL- 1  can be electrically connected to each other by a first Y-touch electrode connecting pattern Y-CL- 1 . A load increase due to a structure that the first Y-touch electrode line Y-TEL- 1  is divided can be prevented by the first Y-touch electrode connecting pattern Y-CL- 1 . 
     At least one first dummy electrode DME 1  can be disposed between the two parts of the first Y-touch electrode line Y-TEL- 1 . 
     The first dummy electrode DME 1  can be disposed to be electrically separated from the first Y-touch electrode line Y-TEL- 1  and the first Y-touch routing line Y-TL- 1 . 
     A boundary of the first dummy electrode DME 1  and the first Y-touch routing line Y-TL- 1  can be different from the boundary of the first sub-area SAA 1  and the second sub-area SAA 2 . The boundary of the first dummy electrode DME 1  and the first Y-touch routing line Y-TL- 1  can be positioned inside of the first sub-area SAA 1 . 
     The first dummy electrode DME 1  can be disposed on the first sub-area SAA 1  to be corresponded to a portion of the first Y-touch routing line Y-TL- 1  disposed on the second sub-area SAA 2 . A width of the first dummy electrode DME 1  can be identical or similar to a width of the first Y-touch routing line Y-TL- 1 . 
     An area of the first Y-touch electrode line Y-TEL- 1  disposed on the first sub-area SAA 1  can be reduced to be corresponding to that an area of the second Y-touch electrode line Y-TEL- 2  is reduced due to an arrangement of the first Y-touch routing line Y-TL- 1  on the second sub-area SAA 2 . An electrode positioned on an area remained according to decreasing an area of the first Y-touch electrode line Y-TEL- 1  can become the first dummy electrode DME 1 . 
     While maintaining touch sensitivity by the touch electrode line TEL disposed on the first sub-area SAA 1  and touch sensitivity by the touch electrode line TEL disposed on the second sub-area SAA 2  to be identical or similar to each other, a structure that some of the touch routing lines TL is disposed on the active area AA can be implemented. 
     As the Y-touch routing line Y-TL is disposed in the second direction, a portion of the Y-touch routing line Y-TL can be positioned on the first boundary BL 1 . 
     As the second boundary BL 2  which is a boundary of the second direction divides the first sub-area SAA 1  and the third sub-area SAA 3 , the second sub-area SAA 2  and the fourth sub-area SAA 4 , the Y-touch routing line Y-TL disposed in the second direction may not be disposed on the second boundary BL 2 . 
     The first Y-touch routing line Y-TL- 1  can be extended from the boundary of the active area AA and the non-active area NA to the non-active area NA and can cross the second Y-touch routing line Y-TL- 2 . On an area where the first Y-touch routing line Y-TL- 1  and the second Y-touch routing line Y-TL- 2  are crossing each other, both can be disposed on different layers. 
     Such as described above, according to embodiments of the present disclosure, the touch sensor structure being capable of reducing the load by the touch electrode line TEL can be provided by a structure that the touch electrode line TEL is divided and disposed on the plurality of sub-areas SAA. Furthermore, as a portion of the touch routing line TL is disposed on the active area AA, a structure being capable of improving the performance of the touch sensing can be provided without the non-active area NA due to an arrangement of the touch routing line TL. 
     The touch electrode TE constituting the touch electrode line TEL, such as an example above-mentioned, can be made of the transparent conductive material, or can be made of the opaque metal material. In the case that the touch electrode TE is the opaque metal material, the touch electrode TE can have a shape that an area corresponding to the light-emitting area of the subpixel SP is opened for not dropping the image display performance of the display panel  110 . The shape of the touch electrode TE including the opened portion can be various according to types of the subpixel SP. 
       FIG.  8    is a diagram illustrating an example of a structure of an electrode constituting a touch sensor structure of the touch display device  100  according to embodiments of the present disclosure.  FIG.  8    exemplary illustrates a structure of an electrode constituting a touch sensor structure on an area indicated by  701  illustrated in  FIG.  7   . 
       FIG.  8    illustrates an example of a specific structure of an electrode constituting the body portion TE-a and the wing portion TE-b of the touch electrode TE above-mentioned. The electrode illustrated in  FIG.  8    is cut in a certain direction, can form the body portion TE-a and the wing portion TE-b of the touch electrode TE. Furthermore, a structure of the touch routing line TL electrically connected to the touch electrode TE can be identical to a structure of the electrode illustrated in  FIG.  8   . 
     Referring to  FIG.  8   , it exemplary illustrates a structure that a display signal line DSL supplying a signal for the display driving is disposed on the display panel  110  and the touch electrode TE is disposed. 
     The display signal line DSL can be include a plurality of first display signal lines DSL 1  disposed in the first direction and a plurality of second display signal lines DSL 2  disposed in the second direction. 
     The first display signal line DSL 1 , for example, can be the gate line GL or the light-emitting control line EML. The second display signal line DSL 2 , for example, can be a data line DL or a line supplying at least one of the first driving voltage VDD, the reference voltage Vref or the second driving voltage VSS. 
     The touch electrode TE, for example, can included a first portion TE_f disposed in the first direction, a second portion TE_s disposed in the second direction and a third portion TE_t disposed in a third direction different from the first direction and the second direction. 
     The electrode constituting the touch electrode TE can be cut in the first direction such as a portion indicated by  801  or can be cut in the second direction such as a portion indicated by  802  for constituting the X-touch electrode TE or the Y-touch electrode Y-TE. 
     The electrode including the first portion TE_f, the second portion TE_s and the third portion TE_t can be cut in the first direction or the second direction, and can constitute the body portion TE-a or the wing portion TE-b of the touch electrode TE above-mentioned. 
     The touch routing line TL can include at least some of the first portion TE_f, the second portion TE_s or the third portion TE_t similarly o the touch electrode TE, and can be cut in the first direction or the second direction. 
     As the touch electrode TE is formed to include the first portion TE_f, the second portion TE_s and the third portion TE_t disposed in different directions one another, the touch electrode TE can include a plurality of opened portions. The shape of the opened portion of the touch electrode TE can be various, and can be determined depending on a shape of the light-emitting area of the subpixel SP disposed on the display panel  110 . 
       FIG.  9    is a diagram illustrating an example of an arrangement relationship of an electrode constituting a touch sensor structure and a configuration included in the subpixel SP in the touch display device  100  according to embodiments of the present disclosure.  FIG.  9    exemplary illustrates a structure of an electrode constituting a touch sensor structure on an area indicated by  702  illustrated in  FIG.  7    according to one embodiment.  FIG.  10    is a diagram illustrating an example of a cross-sectional structure of A-A′ portion illustrated in  FIG.  9    according to one embodiment. 
     Referring to  FIGS.  9  and  10   , the light-emitting area of the light-emitting element ED disposed on the subpixel SP can be positioned on an area overlapping the opened portion of the touch electrode TE. 
     The light-emitting area of the light-emitting element ED can mean an area where the light-emitting layer EL and the second electrode E 2  are disposed to overlap on the first electrode E 1  of the light-emitting element ED. Furthermore, the light-emitting area of the light-emitting element ED can mean an area where a bank BNK is not disposed among an area where the first electrode E 1  of the light-emitting element ED is disposed. 
       FIG.  9    illustrates an example of a shape that the light-emitting areas of a red subpixel SP_r, a green subpixel SP_g and a blue subpixel SP_b are disposed, a shape and a size of the subpixel SP constituting one pixel can be various depending on the display panel  110 . 
     The first portion TE_f, the second portion TE_s and the third portion TE_t of the touch electrode TE can be disposed to avoid the light-emitting area of the subpixel SP. 
     The touch electrode TE can be disposed between the light-emitting areas of adjacent subpixels SP and can prevent or reduce that the touch electrode TE affects the image displaying according to a viewing angle. 
     As the touch electrode TE is disposed to avoid the light-emitting area of the subpixel SP, thus the touch electrode TE can be disposed to overlap a certain structure positioned on the subpixel SP. 
     For example, the first portion TE_f of the touch electrode TE disposed in the first direction can be disposed to overlap at least a portion of the contact hole CH for an electrical connection between the first electrode E 1  of the light-emitting element ED and a thin film transistor TFT on the subpixel SP. 
     Referring to  FIG.  9    and &lt;EX 1&gt; of  FIG.  10   , a multi buffer layer MB can be disposed on a substrate SUB. The substrate SUB, for example, can include a first polyimide layer PI 1 , an interlayer polyimide layer IPD and a second polyimide layer PI 2 . The multi buffer layer MB can be a structure that a plurality of insulating layers are laminated. 
     A light shield metal layer BSM can be disposed on the multi buffer layer MB. The light shield metal layer BSM can constitute the display signal line DSL, or can constitute a portion of the storage capacitor Cstg disposed on the subpixel SP. 
     An active buffer layer AB can be disposed on the light shield metal layer BSM. 
     An active layer ACT can be disposed on the active buffer layer AB. The active layer ACT can be made of a semiconductor material. 
     The active layer ACT can constitute a channel of the thin film transistor TFT. Furthermore, the active layer ACT can constitute the display signal line DSL or the portion of the storage capacitor Cstg by being conductive. 
     A gate insulating layer GI can be disposed on the active layer ACT. 
     A gate metal layer GAT can be disposed on the gate insulating layer GI. The gate metal layer GAT can constitute a gate electrode of the thin film transistor TFT, or can constitute the display signal line DSL, or the like. 
     A first interlayer insulating layer ILD 1  can be disposed on the gate metal layer GAT. 
     A display auxiliary electrode layer TM can be disposed on the first interlayer insulating layer ILD 1 . The display auxiliary electrode layer TM can be used variously for constituting the display signal line DSL or the portion of the storage capacitor Cstg or the like. 
     A second interlayer insulating layer ILD 2  can be disposed on the display auxiliary electrode layer TM. 
     A source drain metal layer SD can be disposed on the second interlayer insulating layer ILD 2 . The source drain metal layer SD can constitute a source electrode and a drain electrode of the thin film transistor TFT, or can constitute the display signal line DSL or the like. 
     A planarization layer PLN can be disposed on the source drain metal layer SD. 
     The first electrode E 1  of the light-emitting element ED can be disposed on the planarization layer PLN. The first electrode E 1  of the light-emitting element ED can be electrically connected to the thin film transistor TFT positioned under the planarization layer PLN thorough the contact hole CH formed in the planarization layer PLN. The thin film transistor TFT electrically connected to the first electrode E 1  of the light-emitting element ED, for example, can be the driving transistor DRT, or can be a transistor controlling the light-emitting timing of the light-emitting element ED such as an example of the  FIG.  2   . 
     The bank BNK can be disposed on the planarization layer PLN and the first electrode E 1  of the light-emitting element ED. The bank BNK can be disposed to cover an edge portion of the first electrode E 1  of the light-emitting element ED. 
     The light-emitting layer EL and the second electrode E 2  of the light-emitting element ED can be disposed on a portion of the first electrode E 1  exposed by the bank BNK and the bank BNK. The portion of the first electrode E 1  exposed by the bank BNK can correspond to the light-emitting area. 
     An encapsulation layer ENCAP can be disposed on the second electrode E 2  of the light-emitting element ED. The encapsulation layer ENCAP can include a plurality of layers. The encapsulation layer ENCAP can include at least one inorganic layer and at least one organic layer. 
     For example, the encapsulation layer ENCAP can include a first inorganic encapsulation layer PAS 1 , an organic encapsulation layer PCL and a second inorganic encapsulation layer PAS 2 . 
     The inorganic encapsulation layer PAS 1 , PAS 2 , for example, can be made of an inorganic insulating material such as silicon nitride SiNx, silicon oxide SiOx, silicon oxynitride SiON or aluminum oxide Al 2 O 3 , which can be deposited at a low temperature. The organic encapsulation layer PCL, for example, can be made of an organic insulating material such as an acrylic resin, an epoxy resin, polyimide, polyethylene or silicon oxycarbon SiOC. 
     The encapsulation layer ENCAP can seal the light-emitting element ED and can protect the light-emitting element ED from an external moisture and air. 
     The touch sensor structure for the touch sensing can be implemented on the encapsulation layer ENCAP. 
     For example, a touch buffer layer TBUF can be disposed on the encapsulation layer ENCAP. The touch buffer layer TBUF can be an inorganic layer. In some cases, the touch buffer layer TBUF may not be disposed, but the touch buffer layer TBUF can be disposed for making it easy to arrange the touch sensor metal TSM on the encapsulation layer ENCAP. 
     A touch insulating layer TILD can be disposed on the touch buffer layer TBUF. 
     Even though  FIG.  10    does not illustrate the second touch sensor metal TSM 2 , but the second touch sensor metal TSM 2  constituting the touch electrode connecting pattern CL or the like can be disposed between the touch buffer layer TBUF and the touch insulating layer TILD. 
     The touch insulating layer TILD can be an inorganic layer. Alternatively, the touch insulating layer TILD can be an organic layer. 
     In the case that the touch insulating layer TILD is an organic layer, a thickness of the touch insulating layer TILD can be greater than a thickness of the touch buffer layer TBUF. 
     Furthermore, in the case that the touch insulating layer TILD is an organic layer, such as &lt;EX 2&gt; of  FIG.  10   , a touch insulating buffer layer TIBUF can be further disposed between the touch insulating layer TILD and the touch buffer layer TBUF. Such as described above, two or more buffer layer can be disposed between the encapsulation layer ENCAP and the touch insulating layer TILD. 
     The touch insulating buffer layer TIBUF can be disposed between the touch insulating layer TILD and the second touch sensor metal TSM 2 . The touch insulating buffer layer TIBUF can be an inorganic layer. The touch insulating buffer layer TIBUF can be made of a same material as the touch buffer layer TBUF. 
     At least a portion of the touch insulating layer TILD can be disposed to contact a top surface of the touch insulating buffer layer TIBUF. 
     As the touch insulating buffer layer TIBUF made of an inorganic layer is disposed between the touch insulating layer TILD and the second touch sensor metal TSM 2 , an adhesion of the touch insulating layer TILD which is an organic layer can become easier. 
     A thickness of the touch insulating buffer layer TIBUF can be smaller than a thickness of the touch insulating layer TILD, and can be similar to a thickness of the touch buffer layer TBUF. 
     The touch electrode TE can be disposed on the touch insulating layer TILD. The first touch sensor metal TSM 1  can be disposed on the touch insulating layer TILD and can constitute the touch electrode TE. Furthermore, the first touch sensor metal TSM 1  can be disposed on the touch insulating layer TILD and can constitute the touch routing line TL. 
       FIG.  10    exemplary illustrates a cross-sectional structure of a portion that the first portion TE_f of the touch electrode TE illustrated in  FIG.  9    is disposed. The first portion TE_f of the touch electrode TE can be disposed on the touch insulating layer TILD. 
     The first portion TE_f of the touch electrode TE can be disposed to avoid the light-emitting area of the light-emitting element ED. Thus, the first portion TE_f of the touch electrode TE is non-overlapping with the light-emitting area. The first portion TE_f of the touch electrode TE can be disposed on an area overlapping at least a portion of the contact hole CH for an electrical connection between the first electrode E 1  of the light-emitting element ED and the thin film transistor TFT. 
     The first portion TE_f of the touch electrode TE can be disposed between adjacent display signal lines DSL disposed in the first direction, or can be disposed to overlap a portion of the display signal line DSL. 
     As the touch electrode TE is positioned on an area overlapping the contact hole CH and is disposed to avoid the light-emitting area of the light-emitting element ED, the touch sensor structure can be implemented without dropping the image display function of the display panel  110 . 
     A touch protective layer TPAS can be disposed on the touch electrode TE made of the first touch sensor metal TSM 1  and can protect the touch electrode TE. 
     Such as described above, as each portion of an electrode constituting the touch electrode TE or the touch routing line TL is disposed on an area not overlapping the light-emitting area of the light-emitting element ED disposed on the subpixel SP and is disposed on a position reducing an interruption of a viewing angle of the light-emitting area, thus the touch sensor structure can be implemented while preventing or reducing reduction of image display performance of the display panel  110 . 
     Below, a specific example that the touch sensor structure illustrated in  FIG.  5    is implemented by the touch electrode TE and the touch routing line TL having an electrode structure above-mentioned will be described. Furthermore, such as described above, the touch electrode TE can have various shapes other than an electrode structure above-mentioned, and embodiments of the present disclosure can be applied to various electrode structures. 
       FIGS.  11  to  13    are diagrams illustrating specific examples that a touch sensor structure of the touch display device  100  is implemented on the active area AA of the display panel  110  according to embodiments of the present disclosure. 
       FIG.  11    illustrates an example of a structure of the touch electrode TE disposed on an area where the sub-areas SAA are divided on the active area AA according to an embodiment.  FIG.  12    illustrates an example of a structure of the touch routing line TL and the dummy electrode DME disposed on the active area AA according to an embodiment.  FIG.  13    illustrates an example of a boundary of the touch routing line TL and the dummy electrode DME on the active area AA according to an embodiment. 
     Referring to  FIG.  11   , the active area AA of the display panel  110  can be divided as the plurality of sub-areas SAA by the first boundary BL 1  and the second boundary BL 2 . The touch electrode line TEL disposed on each of the plurality of sub-areas SAA can be disposed to be separated from each other. A schematic diagram illustrating an overall structure of the display panel  110  in  FIG.  11    illustrates portions made of the first touch sensor metal TSM 1  for a convenience of an illustration. 
     Some of the touch electrode lines TEL disposed on the plurality of sub-areas SAA can be electrically connected to the touch routing line TL disposed on the non-active area NA on the boundary of the active area AA and the non-active area NA. 
     Other some of the touch electrode lines TEL disposed on the plurality of sub-areas SAA can be electrically connected to the touch routing line TL disposed to pass the active area AA from the non-active area NA on the active area AA. 
     The touch electrode TE constituting the touch electrode line TEL can include at least one body portion TE-a and the plurality of wing portions TE-b. 
     The touch electrode line TEL and the touch routing line TL can be implemented by cutting an electrode including the first portion TE_f, the second portion TE_s and the third portion TE_t in a certain direction. 
     For example, an electrode can be cut on a boundary of the X-touch electrode line X-TEL and the Y-touch electrode line Y-TEL. The electrode can be cut on a boundary of the touch routing line TL, the dummy electrode DME and the touch electrode line TEL. Furthermore, the electrode can be cut on a boundary of the sub-area SAA. 
     Referring to  FIG.  11   , an electrode can be cut in the first direction on the first boundary BL 1 . The electrode can be cut in the second direction on the second boundary BL 2 . 
     By cutting the electrode on the first boundary BL 1  and the second boundary BL 2 , the touch electrode line TEL disposed on each of the first sub-area SAA 1 , the second sub-area SAA 2 , the third sub-area SAA 3  and the fourth sub-area SAA 4  can be divided. 
     The X-touch electrode line X-TEL and the Y-touch electrode line Y-TEL disposed on each sub-area SAA can be implemented by cutting the electrode in the first direction or the second direction. 
     A space between the touch electrodes TE on the boundary of the sub-area SAA can be identical or similar to a space between the touch electrodes TE inside of the sub-area SAA. As a space between electrodes cut is substantially identical, a difference of visibility may not be generated according to regions of the display panel  110 . 
     The touch routing line TL and the dummy electrode DME can be implemented by cutting an electrode as a similar method to the touch electrode line TEL. 
     Referring to  FIG.  12   , a portion indicated by  1201  illustrates an example of an area where the first dummy electrode DME 1  is disposed on the first sub-area SAA 1 . A portion indicated by  1202  illustrates an example of an area where the first Y-touch routing line Y-TL- 1  is disposed on the second sub-area SAA 2 . 
     The first Y-touch routing line Y-TL- 1  can be disposed by cutting an electrode disposed on the second sub-area SAA 2 . 
     The first Y-touch routing line Y-TL- 1  can be positioned between two parts of the second Y-touch electrode line Y-TEL- 2  on the second sub-area SAA 2 . 
     At least one first dummy electrode DME 1  can be disposed by cutting an electrode disposed on the first sub-area SAA 1 . The at least one first dummy electrode DME 1  can be positioned on an area corresponding to an area where the first Y-touch routing line Y-TL- 1  is disposed on the second sub-area SAA 2  in the first sub-area SAA 1 . 
     The first dummy electrode DME 1  can be positioned between the first Y-touch electrode line Y-TEL- 1  on the first sub-area SAA 1 . The plurality of first dummy electrodes DME 1  can be separated from each other and can be disposed such as an example illustrated in  FIG.  12    so that a defect is not occurred even if a portion of the first dummy electrode DME 1  is shorted. 
     The first dummy electrode DME 1  electrically separated from the first Y-touch electrode line Y-TEL- 1  can be positioned between the first Y-touch electrode line Y-TEL- 1  of the first sub-area SAA 1 . The first Y-touch routing line Y-TL- 1  electrically separated from the second Y-touch electrode line Y-TEL- 2  can be positioned between the second Y-touch electrode line Y-TEL- 2  of the second sub-area SAA 2 . 
     The first dummy electrode DME 1  and the first Y-touch routing line Y-TL- 1  can be disposed to be corresponded to each other. A width of an area where the first dummy electrode DME 1  is disposed can be identical or similar to a width of an area where the first Y-touch routing line Y-TL- 1  is disposed. That is, the lower side touch sensor portion can include an area where the first Y-touch routing line Y-TL- 1  of the upper side touch sensor portion passes, and in the upper side touch sensor portion, the first dummy electrode DME 1  can be provided on an area corresponding to the first Y-touch routing line Y-TL- 1  disposed on the lower side touch sensor portion. 
     At least one second dummy electrode DME 2  can be disposed by cutting an electrode portion between the first Y-touch routing line Y-TL- 1  and the second Y-touch electrode line Y-TEL- 2  on the second sub-area SAA 2 . 
     The second dummy electrode DME 2  can be disposed to be electrically separated from the first Y-touch routing line Y-TL- 1  and the second Y-touch electrode line Y-TEL- 2 . 
     The first dummy electrode DME 1  can be positioned on a portion of the first sub-area SAA 1  corresponding an area where the second dummy electrode DME 2  is disposed on the second sub-area SAA 2 . Some of the first dummy electrodes DME 1  can be disposed to be corresponded to the second dummy electrode DME 2 . 
     The second dummy electrode DME 2  can be disposed to prevent or reduce a drop of visibility due to an arrangement of the touch electrode line TEL. Alternatively, the second dummy electrode DME 2  can be disposed to prevent a short circuit between the first Y-touch routing line Y-TL- 1  and the second Y-touch electrode line Y-TEL- 2 . 
     The first dummy electrode DME 1  can be disposed, or the first Y-touch routing line Y-TL- 1  and the second dummy electrode DME 2  can be disposed on an area corresponding to each other on the first sub-area SAA 1  and the second sub-area SAA 2 . An area of the area where the Y-touch electrode line Y-TEL is disposed on each of the first sub-area SAA 1  and the second sub-area SAA 2  can be identical or similar. A space between two parts of the first Y-touch electrode line Y-TEL- 1  disposed separately on both sides of the first dummy electrode DME 1  on the first sub-area SAA 1  can be identical or similar to a space between two parts of the second Y-touch electrode line Y-TEL- 2  disposed separately on both sides of the first Y-touch routing line Y-TL- 1  on the second sub-area SAA 2 . 
     The first dummy electrode DME 1  and the second dummy electrode DME 2  can be disposed by cutting an electrode similarly with the touch electrode line TEL or the touch routing line TL. The dummy electrode DME can be disposed by cutting an electrode in the first direction or the second direction similarly with the touch electrode line TEL or the like. 
     Alternatively, at least one of the first dummy electrode DME 1  or the second dummy electrode DME 2  can be disposed to be cut in different direction from a direction that the touch electrode line TEL and the touch routing line TL are cut. 
     For example, the touch electrode line TEL and the touch routing line TL, such as described above, can be disposed by cutting an electrode in the first direction or the second direction. Whereas, the first dummy electrode DME 1  and the second dummy electrode DME 2  can be disposed by cutting an electrode in a direction other than the first direction and the second direction. Both sides (ends) of each of the first dummy electrode DME 1  and the second dummy electrode DME 2  can be a shape cut in the third direction different from the first direction and the second direction. 
     For example, the dummy electrode DME can be disposed by cutting an electrode in a diagonal direction on a boundary of the dummy electrode DME and the touch electrode line TEL or the touch routing line TL. Both sides of the dummy electrode DME can be a shape cut in the diagonal direction. In the case that a boundary of the dummy electrode DME is a shape cut in the diagonal direction, an area of an end portion of the dummy electrode DME can be greater than an area of an end portion of the touch electrode line TEL or an end portion of the touch routing line TL. 
     A boundary between the touch electrode line TEL and the touch electrode line TEL, a boundary between the touch electrode line TEL and the touch routing line TL can be shapes that an electrode is cut in the first direction or the second direction. 
     A boundary between the dummy electrode DME and the touch electrode line TEL, a boundary between the dummy electrode DME and the touch routing line TL, and a boundary between the dummy electrodes DME can be shapes cut in the third direction (e.g., the diagonal direction) different from the first direction and the second direction. 
     The dummy electrode DME can have a shape that an electrode is cut in the diagonal direction on a boundary of the dummy electrode DME. The touch electrode line TEL or the touch routing line TL can include a protrusion which protrudes toward the dummy electrode DME and has a shape cut in the diagonal direction on a boundary of the dummy electrode DME and the touch electrode line TEL or the touch routing line TL. 
     As a cutting direction of a boundary of the dummy electrode DME is different from a cutting direction of a boundary of the touch electrode line TEL or the touch routing line TL, a repair process can be easier in an inspection process of the touch sensor structure. 
     For example, in the case that a shorted portion between electrodes is present on a boundary that electrodes are cut in the first direction or the second direction, the repair process to cut the shorted portion is necessary since the corresponding area is a boundary between the touch electrode lines TEL or a boundary between the touch electrode line TEL and the touch routing line TL. 
     In the case that a shorted portion between electrodes is present on a boundary that the electrodes are cut in the diagonal direction, as at least one of the shorted electrodes is the dummy electrode DME, it may not affect the touch sensor structure even if the shorted portion is not cut. Thus, the inspection process can be terminated without the repair process. In this case, the dummy electrode DME can be disposed as a structure that the dummy electrode DME is connected to the touch electrode line TEL or the touch routing line TL on the active area AA. 
     Such as described above, by the arrangement of the dummy electrode DME, an area of the touch electrode line TEL can be uniform, and visibility can be improved. Furthermore, as a cutting direction on a boundary of the dummy electrode DME is different from a cutting direction on a boundary of the touch electrode line TEL or the like, an efficiency of the inspection process can be increased. 
     Although examples above-mentioned describe cases that the dummy electrode DME is disposed on an area corresponding to the touch routing line TL or a periphery of the touch routing line TL only, in some cases, the dummy electrode DME can be disposed inside of the touch electrode line TEL or a boundary area between the touch electrode lines TEL. In this case, the dummy electrode DME can be positioned uniformly on each area. 
     A boundary between the first dummy electrode DME 1  disposed on the first sub-area SAA 1  and the first Y-touch routing line Y-TL- 1  electrically connected to the first Y-touch electrode line Y-TEL- 1  of the first sub-area SAA 1  can be cut in a similar manner. 
     Referring to  FIG.  13   , a portion indicated by  1301  represents a boundary between the first Y-touch routing line Y-TL- 1  and the first dummy electrode DME 1 . 
     A boundary between the first Y-touch routing line Y-TL- 1  and the first dummy electrode DME 1  can be a shape that an electrode is cut in the diagonal direction. 
     Alternatively, in some cases, a boundary between the first Y-touch routing line Y-TL- 1  and the first dummy electrode DME 1  can be a shape cut in the first direction. As a plurality of first dummy electrodes DME 1  are disposed to be separated from each other, only a boundary of the first dummy electrode DME 1  which is the most adjacent to the first Y-touch routing line Y-TL- 1  may not be a shape cut in the diagonal direction. 
     As the first Y-touch routing line Y-TL- 1  is electrically connected to the first Y-touch electrode line Y-TEL- 1  disposed on the first sub-area SAA 1 , a boundary between the first Y-touch routing line Y-TL- 1  and the first dummy electrode DME 1  can be different from a boundary between the first sub-area SAA 1  and the second sub-area SAA 2 . For example, the boundary between the first Y-touch routing line Y-TL- 1  and the first dummy electrode DME 1  can be positioned inside of the first sub-area SAA 1 . 
     The first Y-touch routing line Y-TL- 1  can be directly connected to the first Y-touch electrode line Y-TEL- 1  inside of the first sub-area SAA 1 . The first Y-touch routing line Y-TL- 1  and the first Y-touch electrode line Y-TEL- 1  can be directly connected to each other since both of them are made of the first touch sensor metal TSM 1 . 
     Alternatively, the first Y-touch routing line Y-TL- 1  can be electrically connected to the first Y-touch electrode line Y-TEL- 1  by the first Y-touch electrode connecting pattern Y-CL- 1  made of the second touch sensor metal TSM 2 . 
     The first Y-touch routing line Y-TL- 1  and the first Y-touch electrode line Y-TEL- 1  can be electrically connected to each other by the first Y-touch electrode connecting pattern Y-CL- 1  positioned on an upper side of the first boundary BL 1 . Two parts of the second Y-touch electrode line Y-TEL- 2  disposed on the second sub-area SAA 2  can be electrically connected to each other by the second Y-touch electrode connecting pattern Y-CL- 2  positioned on a lower side of the first boundary BL 1 . 
     In the case that the first Y-touch routing line Y-TL- 1  and the first Y-touch electrode line Y-TEL- 1  are connected by the first Y-touch electrode connecting pattern Y-CL- 1 , the first Y-touch routing lien Y-TL-a and the first Y-touch electrode line Y-TEL- 1  can be connected to each other or can be separated from each other on a layer where the first touch sensor metal TSM 1  is disposed. 
     In the case that the first Y-touch routing line Y-TL- 1  and the first Y-touch electrode line Y-TEL- 1  are disposed to be separated from each other on a layer where the first touch sensor metal TSM 1  is disposed, a boundary between the first Y-touch routing line Y-TL- 1  and the first Y-touch electrode line Y-TEL- 1  can be a diagonal shape. As the repair process for cutting is not required even if the first Y-touch routing line Y-TL- 1  and the first Y-touch electrode line Y-TEL- 1  made of the first touch sensor metal TSM 1  are shorted, a boundary between the first Y-touch routing line Y-TL- 1  and the first Y-touch electrode line Y-TEL- 1  made of the first touch sensor metal TSM 1  can be cut in the diagonal direction in a process cutting the dummy electrode DME for a convenience of the process. 
     Such as described above, the first Y-touch routing line Y-TL- 1  and the first Y-touch electrode line Y-TEL- 1  can be electrically connected to each other as various shapes on the first sub-area SAA 1 . 
       FIGS.  14  to  17    are diagrams illustrating a specific example that a touch sensor structure of the touch display device  100  according to embodiments of the present disclosure is implemented on a peripheral area of a boundary of the active area AA and the non-active area NA of the display panel  110 . 
       FIG.  14    illustrates a peripheral area of a boundary of the active area AA and the non-active area NA positioned adjacently to the first sub-area SAA 1  on one side (e.g., a left side) of the display panel  110  according to one embodiment.  FIG.  15    illustrates a peripheral area of a boundary of the active area AA and the non-active area NA positioned adjacently to the third sub-area SAA 3  on other side (e.g., a right side) of the display panel  110  according to one embodiment.  FIG.  16    exemplary illustrates a specific structure which the second touch sensor metal TSM 2  is disposed in an example illustrated in  FIG.  14   .  FIG.  17    illustrates a peripheral area of a boundary of the active area AA and the non-active area NA positioned adjacently to the second sub-area SAA 2  on a lower side of the display panel  110  according to one embodiment. 
     Referring to  FIG.  14   , a first X-touch electrode contact pad X-CP- 1  and the first X-touch routing line X-TL- 1  electrically connected to the first X-touch electrode line X-TEL- 1  can be disposed on a boundary of the active area AA and the non-active area NA on the first sub-area SAA 1 . 
     The first X-touch electrode line X-TEL- 1  can be made of the first touch sensor metal TSM 1 . 
     Such as an example of a cross-sectional structure of C-C′ portion illustrated in  FIG.  14   , the first X-touch electrode line X-TEL- 1  can be extended from the active area AA to the non-active area NA, and can be electrically connected to the first X-touch electrode contact pad X-CP- 1  made of the second touch sensor metal TSM 2  through the contact hole CH. Alternatively, a portion made of the first touch sensor metal TSM 1  which is extended to the non-active area NA to be connected to the first X-touch electrode contact pad X-CP- 1  can be a part of the first X-touch electrode contact pad X-CP- 1 . 
     A portion of the first X-touch electrode contact pad X-CP- 1  made of the second touch sensor metal TSM 2  can be connected to the first X-touch electrode connecting pattern X-CL- 1  disposed on the active area AA. 
     An example illustrated in  FIG.  14    illustrates an example that the first X-touch electrode connecting pattern X-CL- 1  is constituted by three lines, but not limited to this. Any number of lines may constitute the first X-touch electrode connecting pattern X-CL- 1 . 
     As the first touch electrode connecting pattern X-CL- 1  is made of the second touch sensor metal TSM 2 , it can be directly connected to the first X-touch electrode contact pad X-CP- 1  positioned on the non-active area NA and can be disposed on the active area AA. The first X-touch electrode connecting pattern X-CL- 1  can be electrically connected to the plurality of X-touch electrodes X-TE on the active area AA and can constitute the first X-touch electrode line X-TEL- 1 . 
     Referring to  FIG.  15   , a third X-touch electrode contact pad X-CP- 3  and a third X-touch routing line X-TL- 3  that is electrically connected to a third X-touch electrode line X-TEL- 3  can be disposed on a boundary of the active area AA and the non-active area NA on the third sub-area SAA 3 . 
     The third X-touch electrode contact pad X-CP- 3  and the third X-touch routing line X-TL- 3  can be disposed similarly to the first X-touch electrode contact pad X-CP- 1  and the first X-touch routing line X-TL- 1  illustrated in  FIG.  14   . The third X-touch electrode contact pad X-CP- 3  and the third X-touch routing line X-TL- 3  can be disposed symmetrically to the first X-touch electrode contact pad X-CP- 1  and the first X-touch routing line X-TL- 1 . 
     Such as an example of a cross-sectional structure of a D-D′ portion illustrated in  FIG.  15   , the third X-touch electrode line X-TEL- 3  can be extended from the active area AA to the non-active area NA, and can be electrically connected to the third X-touch electrode contact pad X-CP- 3  made of the second touch sensor metal TSM 2  through the contact hole CH. 
     Such as described above, a structure that the X-touch electrode contact pad X-CP and the X-touch routing line X-TL are disposed can be similar on both sides of the active area AA. 
     Whereas, a structure that the X-touch electrode line X-TEL is disposed can be different on end portions of the both sides of the active area AA. 
     For example, such as a portion indicated by  1401  in  FIG.  14   , on a boundary of one side of the active area AA, the first X-touch electrode line X-TEL- 1  can be a shape (e.g., a non-opened portion) that a triangle area corresponding to a portion opened as a rhombus shape is filled with the first touch sensor metal TSM 1 . 
     Such as a portion indicated by  1501  in  FIG.  15   , on a boundary of other side of the active area AA, the third X-touch electrode line X-TEL- 3  can be a shape (e.g., a non-opened portion) that a triangle area corresponding to a portion opened as a trapezoid shape is filled with the first touch sensor metal TSM 1 . 
     That is, an opened portion in the touch electrode line TEL can be disposed according to a certain pattern to be disposed to correspond on both sides of the active area AA, and a shape of the non-opened portion which the portion opened is filled with the first touch sensor metal TSM 1  can be different on both sides of the active area AA. 
     When the touch electrode TE disposed to contact one side boundary of the active area AA is referred as a first boundary touch electrode and the touch electrode TE disposed to contact another side boundary of the active area AA is referred as a second boundary touch electrode, a shape of an end portion of the first boundary touch electrode which contacts the one side boundary of the active area AA can be different from a shape of an end portion of the second boundary touch electrode which contacts the other side boundary of the active area AA. 
     As the touch electrode line TEL includes an opened portion in order to correspond to the light-emitting area of the light-emitting element ED, a structure of the touch electrode line TEL can be different on both sides of the active area AA according to an arrangement structure of the light-emitting area of the light-emitting element ED. 
     As the light-emitting area of the light-emitting element ED is repeated as a constant pattern, a structure of the touch electrode line TEL is different on both sides of the active area AA but can be shapes related to each other. For example, a portion indicated by  1401  in  FIG.  14    and a portion indicated by  1501  in  FIG.  15    can be shapes engaged with each other. 
     Furthermore, above-mentioned structure exemplary illustrates a structure of the X-touch electrode line X-TEL, but according to a structure that the light-emitting area of the light-emitting element ED is disposed, it can be also applied to a case of a structure of the Y-touch electrode line Y-TEL positioned on both sides of the active area AA. For example, in some cases, a structure of an end portion of the Y-touch electrode line Y-TEL positioned on an upper side boundary of the active area AA can be different from a structure of an end portion of the Y-touch electrode line Y-TEL positioned on a lower side boundary of the active area AA. 
     Furthermore, according to a structure that the light-emitting area of the light-emitting element ED is disposed, shapes of both end portions of the touch electrode line TEL disposed in one direction can be different from each other, and shapes of both end portions of the touch electrode line TEL disposed in other direction can be identical or correspond to each other. In the case of the examples illustrated in  FIG.  14    and  FIG.  15   , as the light-emitting area of the light-emitting element ED is separated by an electrode portion disposed in the first direction, a shape of an end portion of the Y-touch electrode line Y-TEL adjacent to an upper side boundary of the active area AA can be identical to a shape of an end portion of the Y-touch electrode line Y-TEL adjacent to a lower side boundary of the active area AA. Thus, both end portions of the X-touch electrode line X-TEL adjacent to both sides boundaries of the active area AA can have different shapes, and both end portions of the Y-touch electrode line Y-TEL adjacent to both sides boundaries of the active area AA can have identical or corresponding shapes. 
     Shapes of the touch electrode line TEL made of the first touch sensor metal TSM 1  can be different on both sides of the active area AA such as described above, but shapes of portions made of the second touch sensor metal TSM 2  can be identical or similar. 
       FIG.  16    illustrates an example of a structure of the second touch sensor metal TSM 2  disposed on an area including one sensing unit SU on one side boundary of the active area AA. 
     The X-touch electrode connecting pattern X-CL for a connection of the X-touch electrode X-TE can be disposed on the active area AA. The X-touch electrode connecting pattern X-CL can be connected to the X-touch electrode contact pad X-CP positioned outside of the active area AA. The X-touch electrode contact pad X-CP can be connected to the X-touch routing line X-TL. 
     At least one Y-touch electrode connecting pattern Y-CL made of the second touch sensor metal TSM 2  can be disposed on an area adjacent to an upper side boundary and a lower side boundary of the sensing unit SU. 
     The Y-touch electrode connecting pattern Y-CL can electrically connect two parts of the Y-touch electrode line Y-TEL separated by the Y-touch routing line Y-TL or the first dummy electrode DME 1 . 
     Two or more Y-touch electrode connecting pattern Y-CL can be disposed on one sensing unit SU, and the Y-touch electrode connecting pattern Y-CL can be disposed on various positions. As the Y-touch electrode connecting pattern Y-CL connects the Y-touch electrode Y-TE separated on an upper side and a lower side of each sensing unit SU, the Y-touch electrode Y-TE can have a similar state to a structure not separated. 
     As the Y-touch electrode connecting pattern Y-CL is positioned on boundaries of an upper side and a lower side of the sensing unit SU, a point that the X-touch electrode contact pad X-CP connected to the X-touch electrode line X-TEL is divided can be positioned between adjacent Y-touch electrode connecting patterns Y-CL. 
     For example, such as a portion indicated by  1601 , a boundary between the X-touch contact pads X-CP can be identical to a boundary of the sensing unit SU. 
     As the Y-touch electrode connecting patterns Y-CL are disposed on both sides of a boundary of the sensing unit SU, a boundary between the X-touch electrode contact pads X-CP can be positioned between adjacent Y-touch electrode connecting patterns Y-CL. 
     A Y-auxiliary routing pattern Y-TLP can be disposed on an area other than an area where the X-touch electrode connecting pattern X-CL and the Y-touch electrode connecting pattern Y-CL are disposed on a layer where the second touch sensor metal TSM 2  is disposed. 
     The Y-auxiliary routing pattern Y-TLP can be disposed to be separated from the X-touch electrode connecting pattern X-CL and the Y-touch electrode connecting pattern Y-CL. The Y-auxiliary routing pattern Y-TLP can be electrically connected to the Y-touch routing line Y-TL overlapping the Y-auxiliary routing pattern Y-TLP and can reduce a resistance of the Y-touch routing line Y-TL disposed on the active area AA. 
     The second touch sensor metal TSM 2  disposed on an area overlapping the first dummy electrode DME 1  can be disposed as a shape similar to the first dummy electrode DME 1  and can constitute a dummy pattern DMP. 
     The dummy pattern DMP can be disposed on an area other than an area where the X-touch electrode connecting pattern X-CL, the Y-touch electrode connecting pattern Y-CL and the Y-auxiliary routing pattern Y-TLP are disposed on a layer where the second touch sensor metal TSM 2  is disposed. As the dummy pattern DMP is disposed on an area overlapping the touch electrode line TEL, a visibility difference with an area where the touch routing line TL and the auxiliary routing pattern TLP are disposed to overlap each other can be prevented or at least reduced. 
     As only the X-touch routing line X-TL driving the X-touch electrode line X-TEL disposed on a corresponding sub-area SAA is disposed on a boundary area of both sides of the active area AA, an arrangement of the X-touch routing line X-TL can be easy. The X-touch routing line X-TL can be made of at least one of the first touch sensor metal TSM 1  or the second touch sensor metal TSM 2  and can be implemented as a shape reducing a line resistance. 
     The touch routing line TL connected to the touch electrode line TEL of the sub-area SAA positioned on an upper side of the active area AA and the touch routing line TL connected to the touch electrode line TEL of the sub-area SAA positioned on a lower side of the active area AA can be disposed on a lower side boundary area of the active area AA. 
     Referring to  FIG.  17   , a first Y-touch electrode contact pad Y-CP- 1  connected to the first Y-touch routing line Y-TL- 1  can be disposed on a boundary of the active area AA and the non-active area NA positioned on a lower side of the second sub-area SAA 2 . Furthermore, a second Y-touch electrode contact pad Y-CP- 2  connected to the second Y-touch electrode line Y-TEL- 2  disposed on the second sub-area SAA 2  can be disposed. 
     The second Y-touch electrode contact pad Y-CP- 2  can connect two parts of the second Y-touch electrode line Y-TEL- 2  positioned on both sides of the first Y-touch routing line Y-TL- 1  each other. The second Y-touch electrode contact pad Y-CP- 2  can be disposed to cross the first Y-touch electrode contact pad Y-CP- 1  connected to the first Y-touch routing line Y-TL- 1 . 
     On an area where the second Y-touch electrode contact pad Y-CP- 2  crosses the first Y-touch electrode contact pad Y-CP- 1 , the second Y-touch electrode contact pad Y-CP- 2  can be disposed by using the first touch sensor metal TSM 1 , the first Y-touch electrode contact pad Y-CP- 1  can be disposed by using the second touch sensor metal TSM 2 . Alternatively, in some cases, they can be disposed conversely to this. 
     Two parts of the second Y-touch electrode line Y-TEL- 2  positioned on both sides of the first Y-touch routing line Y-TL- 1  can be electrically connected by the second Y-touch electrode connecting pattern Y-CL- 2  made of the second touch sensor metal TSM 2  on an area adjacent to a boundary of the active area AA. 
     Furthermore, two parts of the second Y-touch electrode line Y-TEL- 2  can be electrically connected to each other by the second Y-touch electrode contact pad Y-CP- 2  on outside of the active area AA. The second Y-touch electrode contact pad Y-CP- 2  can be disposed along an outer edge of each of two parts of the second Y-touch electrode line Y-TEL- 2 . The second Y-touch electrode contact pad Y-CP- 2  can be disposed such that a part made of the first touch sensor metal TSM 1  and a part made of the second touch sensor metal TSM 2  are electrically connected to each other through the contact hole CH positioned on outside of the active area AA. 
     A structure that the first Y-touch routing line Y-TL- 1  disposed on the active area AA is extended to the non-active area NA and the second Y-touch electrode line Y-TEL- 2  is connected to the second Y-touch routing line Y-TL- 2  can be provided while reducing a load increase by a separated structure of the second Y-touch electrode line Y-TEL- 2 . 
     At least one third dummy electrode DME 3  can be disposed on the non-active area NA adjacent to the active area AA. 
     The third dummy electrode DME 3 , for example, can be disposed on an area other than an area where the Y-touch electrode contact pad Y-CP and the Y-touch routing line Y-TL are disposed on the non-active area NA. A remained portion in a process of cutting an electrode for constituting the Y-touch electrode contact pad Y-CP and the Y-touch routing line Y-TL can be disposed as the third dummy electrode DME 3 . 
     As the third dummy electrode DME 3  is positioned between the first Y-touch electrode contact pad Y-CP- 1  and the second Y-touch electrode contact pad Y-CP- 2 , a short circuit defect between the first Y-touch electrode contact pad Y-CP- 1  and the second Y-touch electrode contact pad Y-CP- 2  can be prevented or at least reduced. 
     Alternatively, in some cases, the third dummy electrode DME 3  can be electrically connected to one of the first Y-touch electrode contact pad Y-CP- 1  or the second Y-touch electrode contact pad Y-CP- 2  and can constitute a portion of the Y-touch electrode contact pad Y-CP. 
       FIG.  18    is a diagram illustrating a specific example that a touch sensor structure of the touch display device  100  is implemented between the active area AA of the display panel  110  and a dam DM of the non-active area NA according to embodiments of the present disclosure. 
     Referring to  FIG.  18   , at least one dam DM can be disposed on the non-active area NA of the display panel  110 . The at least one dam DM can be disposed to surround the active area AA. The at least one dam DM can be positioned on an outer portion of the encapsulation layer ENCAP. The at least one dam DM can be a part of the encapsulation layer ENCAP. 
     The plurality of touch routing lines TL can be positioned inside of the at least one dam DM on the non-active area NA. The plurality of touch routing line TL can be positioned between the active area AA and the at least one dam DM on area other than a pad area PA. 
     As the plurality of touch routing lines TL are positioned inside of the at least one dam DM, the touch routing line TL can be disposed while reducing an increase of the non-active area NA. 
     At least one shield line SHL can be disposed to surround at least a portion of the plurality of touch routing line TL. The shield line SHL can be positioned between the touch routing line TL positioned outermost of the plurality of the touch routing lines TL and the dam DM. 
     The shield line SHL can be made of a same material to the touch routing line TL. For example, the shield line SHL can be made of at least one of the first touch sensor metal TSM 1  or the second touch sensor metal TSM 2 . 
     The shield line SHL can be grounded. Alternatively, the shield line SHL can receive a signal different from a signal supplied through the touch routing line TL. 
     As the shield line SHL is disposed to encompass outside of the touch routing line TL, the shield line SHL can block an external noise and can prevent or reduce that the external noise affect a signal of the touch routing line TL. 
     At least one guard line GUL can be disposed between the touch routing line TL and the shield line SHL. 
     The guard line GUL can be made of a same material to the touch routing line TL. For example, the guard line GUL can be made of at least one of the first touch sensor metal TSM 1  or the second touch sensor metal TSM 2 . 
     As the guard line GUL is positioned between the touch routing line TL and the shield line SHL, the guard line GUL can block that a parasitic capacitance is formed between the touch routing line TL and the shield line SHL. As the parasitic capacitance between the touch routing line TL and the shield line SHL is blocked, it can be blocked that a fluctuation of a signal or a voltage state of the shield line SHL affects the touch routing line TL. 
     The guard line GUL can be supplied a signal corresponding to a signal applied to the touch routing line TL positioned the most adjacent to the guard line GUL among the plurality of touch routing lines TL. The guard line GUL can be supplied a signal corresponding to a signal applied to the touch routing line TL positioned outmost among the plurality of touch routing lines TL. 
     A signal corresponding to a signal applied to the touch routing line TL can mean a signal which is identical to at least one of a frequency, an amplitude or a phase of a signal applied to the touch routing line TL. 
     For example, the guard line GUL can be supplied a signal identical to a signal applied to the touch routing line TL positioned the most adjacent to the guard line GUL at an identical timing. A parasitic capacitance may not be formed between the touch routing line TL positioned the most adjacent to the guard line GUL and the guard line GUL. An indirect noise by the shield line SHL can be blocked by the guard line GUL. 
     Such as described above, it can be blocked by the shield line SHL that an external noise affects the touch routing line TL directly. Furthermore, it can be blocked by the guard line GUL that an indirect noise by the shield line SHL affects the touch routing line TL. A noise of a signal detected through the touch routing line TL can be prevented or reduced by the shield line SHL and the guard line GUL, and a signal difference according to positions of the touch routing lines TL can be prevented or reduced. 
     At least one of the shield line SHL or the guard line GUL can be disposed to be divided on the non-active area NA. 
     For example, the shield line SHL and the guard line GUL, such as a portion indicated by  1801 , can be disposed to be divided on an extended line of the second boundary BL 2 . 
     The touch electrode line TEL disposed on the first sub-area SAA 1  and the touch electrode line TEL disposed on the third sub-area SAA 3  can be disposed to be separated from each other and can be driven independently. A minute difference of driving timings of the touch routing lines TL supplying signals to the touch electrode lines TEL disposed on each of the first sub-area SAA 1  and the third sub-area SAA 3  can be present. 
     The guard line GUL being supplied a signal corresponding to a signal applied to the touch routing line TL can be disposed to be divided to be corresponded to the sub-area SAA driven by the corresponding touch routing line TL. 
     For example, as the guard line GUL positioned on sides of the first sub-area SAA 1  and the second sub-area SAA 2  of the display panel  110  is the most adjacent to the touch routing line TL driving the first sub-area SAA 1 , it can be disposed to surround outside of the first sub-area SAA 1 . 
     As the guard line GUL positioned on sides of the third sub-area SAA 3  and the fourth sub-area SAA 4  of the display panel  110  is the most adjacent to the touch routing line TL driving the third sub-area SAA 3 , it can be disposed to surround outside of the third sub-area SAA 3 . 
     Each guard line GUL positioned on both sides of the display panel  110  can be supplied a signal corresponding to a signal applied to the touch routing line TL at a timing that a signal is applied to adjacent touch routing line TL. 
     In a structure that the touch electrode line TEL disposed on the active area AA is divided as the sub-area SAA and driven, a noise to the touch routing line TL driving each sub-area SAA can be blocked more accurately. 
     Examples above-mentioned are examples that the guard line GUL is divided in a structure that the active area AA is divided as four sub-areas SAA, but the guard line GUL can be disposed to be divided variously according to a divided structure of the sub-area SAA. 
     Furthermore, the shield line SHL positioned outside of the guard line GUL can be disposed to be divided to correspond to a divided structure of the guard line GUL. 
     For example, the shield line SHL can be disposed to be divided on an extended line of the second boundary BL 2 . Alternatively, in some cases, the shield line SHL can be disposed not to be divided. 
     Grounded shield line SHL can disposed to surround lines disposed on the non-active area NA and can block an external noise. The guard line GUL positioned adjacent to the touch routing line TL can be disposed to be divided to be corresponded to the touch routing line TL or the sub-area SAA driven by the touch routing line TL, and can block a parasitic capacitance between lines, and can improve an effect of a noise blocking. 
     At least one of the touch routing line TL, the guard line GUL or the shield line SHL disposed on the non-active area NA can be electrically connected to a pad disposed on the pad area PA and can be supplied a signal. 
       FIG.  19    is a diagram illustrating a specific example that a touch sensor structure of the touch display device  100  is implemented on the non-active area NA including the pad area PA of the display panel  110  according to embodiments of the present disclosure. 
     Referring to  FIG.  19   , the pad area PA where a plurality of pads are disposed can be positioned on at least one side of the display panel  110 . 
     A plurality of display pads electrically connected to lines supplying a signal for the display driving and a plurality of touch pads TP electrically connected to lines supplying a signal for the touch sensing can be disposed on the pad area PA. 
     The plurality of touch routing lines TL can be extended from the active area AA to the non-active area NA and can pass over the dam DM. The touch routing line TL can pass over the dam DM and can be electrically connected to the touch pad TP disposed on the pad area PA. 
     The plurality of display signal lines DSL can be disposed to be extended from the active area AA to the non-active area NA. As the display signal line DSL is disposed under the encapsulation layer ENCAP, it can be disposed to pass under the dam DM. The display signal line DSL can be electrically connected to the display pad disposed on the pad area PA. 
     At least some of each of the display pads and the touch pads TP can be disposed by using a material constituting the touch electrode TE and the touch routing line TL. At least some of each of the display pads and the touch pads TP can be disposed by using a material constituting the display signal line DSL. 
     Various pads can be constituted by electrically connecting a pad portion made of the material constituting the touch electrode TE and the touch routing line TL and a pad portion made of the material constituting the display signal line DSL on the pad area PA. 
     A plane structure that the display pad and the touch pad TP are disposed can be various according to a position of the pad area PA. 
     For example, the pad area PA can be divided to correspond to the sub-area SAA of the active area AA. For example, the pad area PA can include four pad areas PA 1 , PA 2 , PA 3 , PA 4 . 
     A gate pad GP supplying a signal or a voltage related to a diving of the gate driving circuit  120 , a data pad DP supplying a signal or a voltage related to a driving of the data driving circuit  130  and the touch pad TP can be disposed on a first pad area PAL 
     The touch pad TP disposed on the first pad area PA 1  can be electrically connected to the X-touch routing line X-TL driving the X-touch electrode line X-TEL disposed on the first sub-area SAA 1  and the second sub-area SAA 2 . In some cases, some of the touch pads TP disposed on the first pad area PA 1  can be electrically connected to the Y-touch routing line Y-TL driving the Y-touch electrode line Y-TEL disposed on the first sub-area SAA 1  and the second sub-area SAA 2 . 
     At least some of the touch pads TP disposed on the first pad area PA 1  can be disposed symmetrically to the display pad. For example, the touch pad TP can be disposed symmetrically to the gate pad GP. In this case, the touch routing line TL connected to the touch pad TP can be disposed symmetrically to the display signal line DSL connected to the gate pad GP. 
     The data pad DP supplying a signal or a voltage related to a driving of the data driving circuit  130  and the touch pad TP can be disposed on the second pad area PA 2  and the third pad area PA 3 . 
     The touch pad TP disposed on each of the second pad area PA 2  and the third pad area PA 3  can be disposed symmetrically. The data pad DP can be disposed between some and others of the touch pad TP disposed symmetrically. 
     The touch pad TP disposed on the second pad area PA 2  can be electrically connected to the Y-touch routing line Y-TL driving the Y-touch electrode line Y-TEL disposed on the first sub-area SAA 1  and the second sub-area SAA 2 . The touch pad TP disposed on the third pad area PA 3  can be electrically connected to the Y-touch routing line Y-TL driving the Y-touch electrode line Y-TEL disposed on the third sub-area SAA 3  and the fourth sub-area SAA 4 . 
     In some cases, some of the touch pads TP disposed on the second pad area PA 2  can be electrically connected to the Y-touch routing line Y-TL driving the third sub-area SAA 3  and the fourth sub-area SAA 4 . Some of the touch pads TP disposed on the third pad area PA 3  can be electrically connected to the Y-touch routing line Y-TL driving the first sub-area SAA 1  and the second sub-area SAA 2 . 
     Furthermore, in some cases, some of the touch pads TP disposed on the second pad area PA 2  can be electrically connected to the X-touch routing line X-TL driving the X-touch electrode line X-TEL disposed on the first sub-area SAA 1  and the second sub-area SAA 2 . Some of the touch pads TP disposed on the third pad area PA 3  can be electrically connected to the X-touch routing line X-TL driving the X-touch electrode line X-TEL disposed on the third sub-area SAA 3  and the fourth sub-area SAA 4 . 
     The touch pad TP, the data pad DP and the gate pad GP can be disposed on the fourth pad area PA 4 . The pads disposed on the fourth pad area PA 4  can be disposed symmetrically to the pads disposed on the first pad area PAL 
     The touch pad TP disposed on the fourth pad area PA 4  can be electrically connected to the X-touch routing line X-TL driving the X-touch electrode line X-TEL disposed on the third sub-area SAA 3  and the fourth sub-area SAA 4 . In some cases, some of the touch pads TP disposed on the fourth pad area PA 4  can be electrically connected to the Y-touch routing line Y-TL driving the Y-touch electrode line Y-TEL disposed on the third sub-area SAA 3  and the fourth sub-area SAA 4 . 
     In the case that the gate driving circuit  120  is disposed on both sides of the display panel  110 , the gate pad GP can be disposed on the first pad area PA 1  and the fourth pad area PA 4 . 
     The data pad DP and the touch pad TP can be disposed to be distributed on each area inside of the gate pad GP and can be disposed to be electrically connected to the data line DL or the touch routing line TL disposed on the active area AA.
