Abstract
A touch display panel including a first substrate, scan lines, data lines, a second substrate, a display medium, a second electrode set and a patterned-common-electrode layer is provided. The scan lines and the data lines are disposed on the first substrate and at least parts of the data lines form a first electrode set including first electrode subsets. The second substrate opposite to the first substrate has a top surface and a bottom surface facing the first substrate. The display medium is sandwiched between the first and the second substrates. The second electrode set disposed on the second substrate includes second electrode subsets arranged along a second direction intersected with the first direction. The patterned-common-electrode layer includes openings is disposed between the first and the second electrode sets. An orthogonal projection of the openings is overlapped with that of the first and the second electrode subsets.
