Touch display device

The invention discloses a touch display device which comprises a first substrate, a second substrate, a display medium, a shading structure and a touch sensing structure. A plurality of first shading parts and a plurality of second shading parts of the shading structure are staggered to define a plurality of sub-pixel regions. The touch sensing structure includes a mesh electrode having a plurality of first netting twines and a plurality of second netting twines interlaced with each other. The plurality of first network lines and the plurality of second network lines have a plurality of intersection points, and the intersection points comprise an intersection point located on the same first network line, a previous intersection point of the intersection point and a next intersection point of the intersection point. In a top view of the touch display device, a first distance is formed between the previous intersection point and the next intersection point in the first direction, a second distance is formed bet
