Claim 11:
12. The method of claim 4, further comprising:
forming a light-shielding film on a base substrate;
performing a splicing exposure process on the light-shielding film by using a fourth mask to form a light-shielding layer,
wherein the fourth mask comprises a light-transmissive region and a non-light-transmissive region, the light-transmissive region comprises a first light-transmissive portion and a second light-transmissive portion opposite to each other, and a third light-transmissive portion and a fourth light-transmissive portion which are opposite to each other and connect the first light-transmissive portion and the second light-transmissive portion, and
a distance from an edge of the first light-transmissive portion close to the second light-transmissive portion to an edge of the second light-transmissive portion close to the first light-transmissive portion is larger than 1/N of a preset width of a view area of the touch substrate, where N is the number of exposures of the splicing exposure process using the fourth mask.
