In this exemplary embodiment, the touch screen TS reduces the reflection of external light. This is because the touch screen TS may include the color filter CF described later.

The first touch electrodes TE1-1, TE1-2, TE1-3, and TE1-4 may extend in the first direction DR1 and may be arranged in the second direction DR2. Each of the first touch electrodes TE1-1, TE1-2, TE1-3, and TE1-4 may have a mesh shape defined by a plurality of touch openings passing through.

The second touch electrodes TE2-1, TE2-2, TE2-3, TE2-4, TE2-5, and TE2-6 extend in the second direction DR2 and are arranged in the first direction DR1.

This is because the first touch electrodes TE1-1, TE1-2, TE1-3, and TE1-4 can be set higher than the second touch electrodes TE2-1, TE2-2, TE2-3, TE2-4, TE2- 5 and TE2-6 Closer to each other, and the first touch electrodes TE1-1, TE1-2, TE1-3, and TE1-4 can cover most of the second touch electrodes TE2-1, TE2-2, TE2-3, TE2-4 , TE2-5 and TE2-6.

Although not shown separately, the electrodes arranged in the first direction DR1 in the shielding electrode may be connected to each other. The shielding electrode STE can block the noise generated by the display panel DP (see FIG. 2A), which may interfere with the second sensing part SP2.

The shielding electrode STE is represented by a dotted line, and the second sensing part SP2 is represented by a solid line. In FIGS. 25C and 25D, the second sensing portion SP2 may have a line width larger than that of the shielding electrode STE, but it is not limited thereto.

As described above, because the color filters are respectively disposed inside the openings of the black matrix of the touch screen, the display device can be made thinner. The color filter can filter the external light, and therefore can reduce the reflection of the external light.

Because the first conductive pattern can be arranged to overlap with the second conductive pattern, the second conductive pattern can avoid noise interference generated by the display panel.
