1. A display substrate, comprising:
a flexible substrate body comprising: a plurality of island-shaped display regions spaced apart from each other, a hollow region disposed between adjacent island-shaped display regions and a connection region for connecting the adjacent island-shaped display regions;
a thickness adjusting layer disposed on light exit sides of the plurality of island-shaped display regions of the flexible substrate body; and
a micro-lens layer disposed on a side of the thickness adjusting layer away from the flexible substrate body,
wherein an orthographic projection of the thickness adjusting layer on the flexible substrate body comprises an orthographic projection of the micro-lens layer on the flexible substrate body, and the orthographic projection of the micro-lens layer on the flexible substrate body is at least partially overlapped with the plurality of island-shaped display regions; the thickness adjusting layer and the micro-lens layer are configured to enlarge an image displayed by the plurality of island-shaped display regions,
wherein at least one island-shaped display region comprises a flexible substrate, and
wherein the display substrate further comprises a first adhesive layer and a first over coat layer sequentially disposed on a side of the micro-lens layer away from the flexible substrate body, and a second adhesive layer and a second over coat layer sequentially disposed on a side of the flexible substrate body away from the micro-lens layer.
