Claim 14:
15. A manufacturing method for a display substrate, the display substrate comprising a display region and a bezel region, the display region comprising a plurality of sub-pixels, the display region comprising a main display region and a plurality of corner display regions, each corner display region comprising a first display region and a second display region, the second display region being located at a side of the first display region far away from the main display region, and a distance between a center point of the first display region and a center point of the main display region is smaller than a distance between a center point of the second display region and the center point of the main display region, the manufacturing method comprising:
forming, on a substrate, a driving structure layer, wherein a structure of the driving structure layer formed in the first display region is different from a structure of the driving structure layer formed in the second display region; and
forming, on the driving structure layer, a light emitting structure layer,
wherein:
the plurality of sub-pixels comprise sub-pixels of the main display region, sub-pixels of the first display region and sub-pixels of the second display region;
the second display region comprises a third sub-region and a fourth sub-region, wherein the third sub-region is located between the fourth sub-region and the first display region, and the fourth sub-region is located at a side of the third sub-region away from the main display region;
the third sub-region is provided with a plurality of first island regions separated from each other, first hole regions disposed between adjacent first island regions and first bridge regions connecting adjacent first island regions, wherein the first island regions are provided with sub-pixels of the first display region, the first bridge regions are provided with connecting wires for implementing signal communication between adjacent first island regions, and the first hole regions are provided with at least one first opening;
the fourth sub-region is provided with a plurality of second island regions separated from each other, second hole regions disposed between adjacent second island regions and second bridge regions connecting adjacent second island regions, wherein the second island regions are provided with sub-pixels of the second display region, the second bridge regions are provided with connecting wires for implementing signal communication between adjacent second island regions, and the second hole regions are provided with at least one second opening;
a pattern of the first opening is different from a pattern of the second opening, and an orthographic projection area of the first opening on the substrate is smaller than an orthographic projection area of the second opening on the substrate;
the pattern of the first opening may be T-shaped or -shaped, and the pattern of the second opening may be I-shaped; and
deformability of the third sub-region to the fourth sub-region is gradually increased.
