Abstract
The present disclosure provides a touch substrate. A plurality of first electrodes (11) spaced apart by a first predetermined distance along a first direction is formed over a substrate (5), with adjacent first electrodes (11) mutually connected via a connection part (111). A plurality of second electrodes (12) spaced apart by a second predetermined distance along a second direction is formed over the substrate (5), with adjacent second electrodes (12) mutually connected via a bridging element (3). An insulating layer (2) is formed between the bridging element (3) and the connection part (111). The insulating layer (2) is formed by oxidizing a metal element sputtered from a target, which is used to form one or more of the connection part (111) and the bridging element (3), in an ambient with oxygen so as to form a metal oxide layer over one of the connection part (111) and the bridging element (3).
