Touch display panel
A touch display panel includes a substrate, a first electrode layer, and a second electrode layer. The first and second electrode layers are disposed on the substrate. The second electrode layer electrically connects to the first electrode layer and includes a plurality of sensing electrodes. Each sensing electrode includes a plurality of first conductive lines and a plurality of second conductive lines connected to each other. The first and second conductive lines are respectively arranged along first and second directions, wherein the second direction is different from the first direction. In one of two adjacent sensing electrodes, the outermost first conductive line has at least one first edge and at least one second edge connected to the first edge. The first edge corresponds to one of the second conductive lines of the other one of the two adjacent sensing electrodes, and has a curved shape.
