ABSTRACT:
A touch substrate includes a transparent substrate having a first surface and a second surface facing the first surface, a plurality of thin film transistor elements disposed on the second surface, and a capacitance touch structure. The capacitance touch structure includes a plurality of parallel first conductive electrodes disposed on the first surface and a plurality of parallel second conductive electrodes disposed on the second surface. The second electrodes cross the first electrodes insulatingly. The first electrodes, the second electrodes and the transparent substrate sandwiched therebetween form a plurality of sensing capacitors.
