Touch sensitivity of TE1-2 and TE1-3 and second touch electrodes TE2-1, TE2-2 and TE2-3.

The combination of the first sensing portion SP1, the first connecting portion CP1, and the second auxiliary electrode STE2 may be defined as a first touch electrode. The first sensing portion SP1 can correspond to the lower sensing portion of the first touch electrode, the first connecting portion CP1 can correspond to the lower connecting portion, and the second auxiliary electrode STE2 can correspond to the upper sensing portion. Similarly, the combination of the second sensing portion SP2, the second connecting portion CP2, and the first auxiliary electrode STE1 may be defined as a second touch electrode.

FIGS. 38A and 38B show the connection relationship between the second auxiliary electrode STE2 and the first sensing portion SP1 in detail. The first sensing portion SP1 may be indicated by a broken line, and the second auxiliary electrode STE2 may be indicated by a solid line. In FIGS. 38A and 38B, the line width of the second auxiliary electrode STE2 may be larger than the line width of the first sensing portion SP1, but is not limited thereto. The second auxiliary electrode STE2 and the first sensing portion SP1 may have the same line width. The second auxiliary electrode STE2 may overlap with the first sensing portion SP1 and may not overlap with the first connecting portion CP1.

As shown in FIG. 38C and FIG. 38D, the second auxiliary electrode STE2 and the first sensing portion SP1 are connected to each other through a plurality of sub-contact holes SCH. Although not shown in FIGS. 38A and 38B, the first shielding portion NSP1 may be disposed above the base surface BS as shown in FIGS. 38C and 38D. The first shielding portion NSP1 may overlap the first sensing portion SP1 and the second auxiliary electrode STE2. The first upper coating layer TS-OC1 may cover the first shielding layer NSP1. The first sensing portion SP1 may be disposed on the first upper coating layer TS-OC1.

The 38C and 38D drawings illustrate the layer structures corresponding to the 33B and 34B, but the layer structure is not limited thereto. The cross-sectional structure corresponding to the "NN" portion of the touch screen TS can be changed to 33C, 33D, 33E, 33F, 33G, 33H, 33I, and 33J. As described above, since the noise shielding layer is disposed to overlap the first conductive pattern and the second conductive pattern, the first conductive pattern and the second conductive pattern can avoid noise interference generated from the display device. Moreover, since the touch electrode can have a mesh shape, the tensile stress and the compressive stress applied to the touch electrode can be reduced and the touch electrode can be prevented from cracking. Furthermore, the color filter filters out extraneous light, thereby reducing the reflection of extraneous light. The insulating layer of the touch screen may include a color filter, and thus the display device may become thinner.

While some of the illustrative embodiments and implementations have been described herein, other embodiments and modifications will be apparent from the description. Therefore, the inventive concept is not limited to the illustrative embodiments, but rather the broad scope and various modifications and equivalent arrangements of the scope of the invention.
