Fig. 6A Therefore, the first connection pattern BSP1, the sensing line SL, and the first, second, and third pads PD1, PD2, and PD3 are disposed on the first insulating layer IL1.

[0113] Specifically, according to an embodiment, the first connection pattern BSP1, the sensing line SL, and each of the first, second, and third pads PD1, PD2, and PD3 include a metal, such as molybdenum, silver, titanium, copper, aluminum, or an alloy thereof.

[0114] According to an embodiment, the sensing lines SL include first, second, and third sensing lines SL1, SL2, and SL3 overlapping the non-active area NAR. Each of the first to third sensing lines SL1 to SL3 includes metal.

[0115] According to an embodiment, each of the first sensing lines SL1 has one end connected to one end of each of the first sensing patterns SP1 and the other end connected to each of the first pads PD1. The first sensing patterns SP1 connected to the ends of the first sensing lines SL1 are first column sensing patterns spaced apart from each other in the first direction DR1.

[0116] According to an embodiment, each of the second sensing lines SL2 has one end connected to one end of each of the second sensing patterns SP2 and the other end connected to each of the second pads PD2. The second sensing patterns SP2 connected to the ends of the second sensing lines SL2 are second column sensing patterns spaced apart from each other in the second direction DR2.

[0117] According to an embodiment, each of the third sensing lines SL3 has one end connected to one end of each of the first sensing patterns SP1 and the other end connected to each of the third pads PD3. The first sensing patterns SP1 connected to the ends of the third sensing lines SL3 are third column sensing patterns spaced apart from each other in the first direction DR1.

[0118] According to an embodiment, the first to third sensing lines SL1 to SL3 receive electrical signals from the first to third pads PD1 to PD3, respectively. The first to third pads PD1 to PD3 are connected to the first to third pads PD3 by reference. Figure 4 The described circuit board PCB receives a driving signal or is electrically connected to a separate circuit board to receive a driving signal.

[0119] According to an embodiment, the first to third sensing lines SL1 to SL3 transmit the driving signals received from the first to third pads PD1 to PD3 to the first and second sensing patterns SP1 and SP2 set in the active area AR. In addition, the first to third sensing lines SL1 to SL3 transmit the external input signals generated in the active area AR to the corresponding pads among the first to third pads PD1 to PD3.

[0120] Reference Figure 7 According to an embodiment, two first sensing patterns SP1, one first connection pattern BSP1 connecting the two first sensing patterns SP1 to each other, two second sensing patterns SP2, and one second connection pattern BSP2 connecting the two second sensing patterns SP2 to each other are shown as examples.

[0121] According to an embodiment of the inventive concept, the first connection pattern BSP1 includes a first branch portion BSL and a second branch portion BSR. The first branch portion BSL and the second branch portion BSR are spaced apart from each other in the first direction DR1. Each of the first branch portion BSL and the second branch portion BSR extends in the second direction DR2. The first connection pattern BSP1 overlaps the second connection pattern BSP2 in a plan view.

[0122] According to an embodiment of the inventive concept, in a plan view, a dummy pattern DMP is disposed between the first sensing pattern SP1 and the second sensing pattern SP2. The dummy pattern DMP is disposed on a boundary between the first sensing pattern SP1 and the second sensing pattern SP2, and has an interval OD between the dummy pattern DMP and each of the first sensing pattern SP1 and each of the second sensing pattern SP2. In other words, the dummy pattern DMP is a floating pattern spaced apart from each of the first sensing pattern SP1 and the second sensing pattern SP2. The dummy pattern DMP prevents the gap between the first sensing pattern SP1 and the second sensing pattern SP2 from being visible.

[0123] In addition, according to the implementation mode, Figure 7 As shown in FIG. 1 , although each of the first sensing pattern SP1, the second sensing pattern SP2, and the dummy pattern DMP has a stepped shape, embodiments of the inventive concept are not limited thereto. For example, each of the first sensing pattern SP1, the second sensing pattern SP2, and the dummy pattern DMP may have a linear shape or a groove shape. Figure 7 The middle dummy pattern DMP has a stepped shape, and thus a sensing surface area for external input increases compared to a different shape having the same surface area. Therefore, an input sensing unit having improved touch sensitivity may be provided.

[0124] Reference Figure 8 According to an embodiment, the first sensing pattern SP1 and the second connection pattern BSP2 are disposed on the encapsulation layer ECL. The second connection pattern BSP2 is covered by the first insulating layer IL1. The first connection pattern BSP1 is disposed on the first insulating layer IL1. A portion of the first sensing pattern SP1 is exposed through a contact hole formed in the first insulating layer IL1. A portion of the first sensing pattern SP1 exposed through the contact hole of the first insulating layer IL1 is connected to the first connection pattern BSP1. Therefore, as Figure 8 As shown in FIG. 2 , two first sensing patterns SP1 spaced apart from each other in the second direction DR2 are electrically connected to each other through the first connection patterns BSP1 .

[0125] According to an embodiment, the first connection pattern BSP1 is covered by the second insulating layer IL2. According to an embodiment of the inventive concept, the first connection pattern BSP1, the sensing line SL, and each of the first, second, and third pads PD1, PD2, and PD3 disposed in the second conductive layer CL2 are deposited on the first insulating layer IL1 through one deposition mask.

[0126] In addition, according to an embodiment, the second insulating layer IL2 is disposed on the first insulating layer IL1 through one deposition mask and overlaps the first connection pattern BSP1, the sensing line SL, and the first, second, and third pads PD1, PD2, and PD3. Therefore, the overall manufacturing process of the display device DD can be simplified to reduce manufacturing costs.

[0127] In addition, according to an embodiment of the inventive concept, the second insulating layer IL2 does not overlap at least a portion of the active region AR. In other words, the second insulating layer IL2 overlaps each of the first connection patterns BSP1 in the second conductive layer CL2 in the active region AR, but does not overlap the remaining region. Therefore, the second insulating layer IL2 does not overlap at least a portion of the first sensing pattern SP1 and the second sensing pattern SP2.

[0128] Fig. 9 yes Figure 6B A magnified view of area BB. Fig.10 It is along Fig. 9 A cross-sectional view taken along line II-II'.

[0129] Reference Fig. 9 According to the embodiment, as an example, reference is shown Figure 6B A portion of the second sensing line SL2 connected to the second sensing pattern SP2 in the sensing pattern is described. Hereinafter, the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c, and the fourth sensing line SL2d in the second sensing line SL2 will be described. In addition, although not shown, the structure of each of the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c, and the fourth sensing line SL2d to be described below is the same as the structure of the remaining sensing lines.

[0130] As described above, according to an embodiment, the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c, and the fourth sensing line SL2d transmit a driving signal to the second sensing pattern SP2. When one of the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c, and the fourth sensing line SL2d is disconnected, the driving signal cannot be transmitted to the sensing pattern associated with the disconnected sensing line. Therefore, the display device has reduced driving reliability.

[0131] However, according to an embodiment of the inventive concept, the first conductive layer CL1 includes a plurality of auxiliary lines respectively electrically contacting the sensing lines SL. In addition, the first conductive layer CL1 includes a plurality of auxiliary pads respectively electrically contacting the first pad PD1, the second pad PD2, and the third pad PD3.

[0132] In detail, according to the implementation mode, refer to Fig.10 , the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c and the fourth sensing line SL2d overlap with the non-active area NAR, and the second sensing pattern SP2 overlaps with the active area AR. According to an embodiment of the inventive concept, the first insulating layer IL1 includes a plurality of first contact holes CH1, second contact holes CH2, third contact holes CH3 and fourth contact holes CH4 respectively overlapping with the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c and the fourth sensing line SL2d. The number of contact holes in the first insulating layer IL1 corresponds to the number of sensing lines.

[0133] According to an embodiment, the first conductive layer CL1 includes a first auxiliary line SP2a, a second auxiliary line SP2b, a third auxiliary line SP2c, and a fourth auxiliary line SP2d contacting the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c, and the fourth sensing line SL2d through the first contact hole CH1, the second contact hole CH2, the third contact hole CH3, and the fourth contact hole CH4, respectively. The number of auxiliary lines provided in the first conductive layer CL1 corresponds to the number of sensing lines.

[0134] In addition, according to an embodiment, the first auxiliary line SP2a, the second auxiliary line SP2b, the third auxiliary line SP2c and the fourth auxiliary line SP2d are directly connected to the second sensing pattern SP2. For example, the first auxiliary line SP2a is connected to one second sensing pattern SP2.

[0135] like Fig.10 As shown in , according to an embodiment, a double-line structure is provided, in which electrical connection is achieved through the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c, and the fourth sensing line SL2d and the first auxiliary line SP2a, the second auxiliary line SP2b, the third auxiliary line SP2c, and the fourth auxiliary line SP2d. Therefore, for example, even if the first sensing line SL2a becomes disconnected, the driving signal can be transmitted to the sensing pattern through the first auxiliary line SP2a that is electrically in contact with the first sensing line SL2a.

[0136] The sensing line may be oxidized by contact with the outside air, and thus, the sensing line may become disconnected due to corrosion. However, according to an embodiment of the inventive concept, each of the first auxiliary line SP2a, the second auxiliary line SP2b, the third auxiliary line SP2c, and the fourth auxiliary line SP2d is made of a transparent conductive oxide and thus prevents oxidation.

[0137] As described above, according to an embodiment, the overall driving reliability of the display device can be improved by a double-line structure between the first auxiliary line SP2a, the second auxiliary line SP2b, the third auxiliary line SP2c and the fourth auxiliary line SP2d and the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c and the fourth sensing line SL2d.

[0138] According to an embodiment, the second insulating layer IL2 covers each of the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c, and the fourth sensing line SL2d and is disposed on the first insulating layer IL1. Specifically, according to an embodiment of the inventive concept, the second insulating layer IL2 overlaps the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c, and the fourth sensing line SL2d located in the non-active area NAR and does not overlap with the remaining area. This is achieved because the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c, and the fourth sensing line SL2d are formed by the above-mentioned one mask. For example, the second insulating layer IL2 has a structure overlapping the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c, and the fourth sensing line SL2d.

In other words, one of the first auxiliary line SP2a, the second auxiliary line SP2b, the third auxiliary line SP2c and the fourth auxiliary line SP2d completely overlaps with one of the first sensing line SL2a, the second sensing line SL2b, the third sensing line SL2c and the fourth sensing line SL2d. Hereinafter, the structure of the second auxiliary line SP2b and the second sensing line SL2b will be mainly described.

[0141] like Fig.11A As shown in FIG. 1 , according to an embodiment, the second auxiliary line SP2 b and the second sensing line SL2 b may contact each other through the contact hole CH. The contact hole CH is formed at the Fig.10 In particular, the contact hole CH has a shape extending along the length of the second auxiliary line SP2b.

[0142] For example, according to the implementation mode, Fig. 11B As shown in FIG. 2 , the second auxiliary line SP2b and the second sensing line SL2b extend in contact with each other in the second direction DR2. A contact hole CH is formed for each of the first auxiliary line SP2a, the second auxiliary line SP2b, the third auxiliary line SP2c, and the fourth auxiliary line SP2d.

[0144] Fig. 12A FIG. 2 shows a structure of a contact hole according to another embodiment of the present invention. Fig. 12A and Fig. 12B , the first insulating layer IL1 includes a plurality of sub-contact holes CHa respectively overlapping the first auxiliary line SP2a, the second auxiliary line SP2b, the third auxiliary line SP2c, and the fourth auxiliary line SP2d. In a plan view, the sub-contact holes CHa are arranged in a longitudinal direction of each of the auxiliary lines and are spaced apart from each other in the longitudinal direction of each of the auxiliary lines. The auxiliary lines will be described mainly based on the connection structure between the second sensing line SL2b and the second auxiliary line SP2b in the second direction DR2, and the remaining sensing lines and the auxiliary lines also have the same structure.

[0147] According to an embodiment, Fig.13 The pads shown in the Figure 6B Hereinafter, reference will be made to Fig.13 The first pad PD1 a , the second pad PD1 b , and the third pad PD1 c of the first pad PD1 are described.

The first pad PD1a, the second pad PD1b, and the third pad PD1c are electrically connected to pads on an external circuit board to receive a driving signal.

[0149] According to an embodiment, the first pad PD1a, the second pad PD1b, and the third pad PD1c may be disposed on the second conductive layer CL2 (see Fig. 6A ), wherein the second conductive layer CL2 is disposed on the first insulating layer IL1.
