Abstract
A touch display panel including a first substrate, a second substrate and a liquid crystal layer is provided. The first substrate includes sensing areas and a non-sensing area outside the sensing areas. Each sensing area is provided with a first electrode thereon. The second substrate includes main spacers, sensing protrusions, first sub-spacers and second sub-spacers. The main spacers are connected to the non-sensing area. The sensing protrusions are corresponding to the sensing area and respectively have a second electrode. A sensing gap exists between each second electrode and the corresponding first electrode. The first sub-spacers are corresponding to the non-sensing area and respectively keep a first sub-spacer gap from the first substrate. The second sub-spacers are corresponding to the non-sensing area and respectively keep a second sub-spacer gap from the first substrate. The sensing gap is greater than the first sub-spacer gap and less than the second sub-spacer gap.
