1. A touch display device, comprising:
a display panel, wherein the display panel comprises a first region, and a second region extending outside the first region on at least one edge of the first region, a length of a boundary line between the first region and the second region being less than a length of the at least one edge, an effective display area of the display panel being disposed in the first region;
a touch panel, wherein the touch panel is disposed on a display side of the display panel, and comprises a touch electrode and a touch signal line electrically connected to the touch electrode, an orthographic projection of the touch electrode on the display panel falling within the first region;
a touch driving circuit disposed on a non-display side of the display panel; and
a touch flexible printed circuit board, wherein the touch flexible printed circuit board comprises a first terminal and a second terminal that are electrically connected, the first terminal being electrically connected to the touch signal line, the touch flexible printed circuit board being bent to the non-display side of the display panel, the second terminal being electrically connected to the touch driving circuit;
wherein an orthographic projection of the first terminal on the display panel falls within the second region;
the first region is approximately in a rectangular shape, the second region comprises at least one sub-track region, wherein the number of sub-track regions is equal to 2, the second region comprises a first sub-track region and a second sub-track region, the first sub-track region and the second sub-track region being respectively disposed on two opposite ends of a first edge of the first region proximal to a fan-out region of the display panel.
