Touch display device

A touch display device, comprising:

• a first substrate having a first surface;
• a second substrate disposed corresponding to the first substrate;
• a pixel array structure disposed between the first substrate and the second substrate, wherein the pixel array structure comprises:
• a scan line extending along a first direction;
• a data line extending along a second direction, wherein the scan line and the data line are crossed;
• and
• a first touch signal line extending along the second direction, wherein the first touch signal line overlaps with the data line;
• and
• a color filter structure disposed between the pixel array structure and the second substrate;
• wherein the color filter structure comprises a plurality of pixel units, the plurality of pixel units comprise a first pixel unit, the first pixel unit comprises a first red unit, a first green unit and a first blue unit arranging along the first direction, wherein the first red unit, the first green unit and the first blue unit are projected on the first surface as a first region, a second region and a third region respectively, the first touch signal line is projected on the first surface as a fourth region, and the fourth region locates between the first region and the second region, or the fourth region locates between the second region and the third region.
