Abstract
The present disclosure provides a touch substrate, a manufacturing method thereof and a touch display device. The touch substrate includes: a base substrate; a touch area on the base substrate; a touch electrode made of nano-silver, the touch electrode including first touch electrodes and second touch electrodes, a first insulating layer located on a side of the touch electrode away from a center of the base substrate, a touch electrode bridge on the first insulating layer, the touch electrode bridge connecting adjacent first touch electrodes and/or adjacent second electrodes by way of a first through-hole penetrating the first insulating layer. An etching liquid applied to the touch electrode bridge is different from the etching liquid applied to the nano-silver. The technical solution of the present disclosure can realize a flexible touch substrate by using nano-silver and a photolithography process.
