Abstract
A touch display panel includes a TFT substrate, a CF substrate disposed above the TFT substrate, a liquid crystal layer sandwiched between the TFT substrate and the CF substrate, and a touch sensor formed on the CF substrate. The touch sensor includes a plurality of first electrodes, a plurality of second electrodes, a plurality of third electrodes, a plurality of bridges and an insulating layer. Each of the second electrodes is continuous, each of the first electrodes is interrupted by the second electrodes to form a plurality of electrode sections, and two adjacent electrode sections of the first electrode are electrically connected via a bridge. A plurality of blank areas are defined and surrounded by the first electrodes and the second electrodes, and the third electrodes are respectively disposed within the blank areas. The first electrodes, the second electrodes and the third electrodes are electrically insulated from each other.
