Abstract
The present disclosure provides a touch substrate, a method for manufacturing the touch substrate and a touch display device. The touch substrate includes a base substrate, a plurality of driving electrodes and a plurality of sensing electrodes arranged at different layers on the base substrate, and a black matrix arranged at a peripheral region of the touch substrate. Orthogonal projections of the driving electrodes onto the base substrate overlap orthogonal projections of the sensing electrodes onto the base substrate at a plurality of first overlapping regions and a plurality of second overlapping regions, an orthogonal projection of the black matrix onto the base substrate overlaps each first overlapping region and does not overlap each second overlapping region, and an effective area of the first overlapping region is smaller than an effective area of the second overlapping region.
