1. A display substrate, comprising:
a first substrate including a pixel electrode layer, the pixel electrode layer including a plurality of pixel electrodes;
a microcup structure layer disposed on a side of the first substrate, the microcup structure layer including a plurality of microcups, each microcup having a first opening and a second opening opposite to the first opening, the first opening is closer to the pixel electrode layer than the second opening and a size of the first opening being greater than a size of the second opening;
an electrophoretic fluid filled in the plurality of microcups, the electrophoretic fluid being incorporated with charged particles; and
a second substrate disposed on a side, away from the first substrate, of the microcup structure layer with the electrophoretic fluid, the second substrate including a common electrode layer,
wherein an orthographic projection of the second opening of each microcup on the second substrate has a shape of a closed figure, and a distance from any point on a boundary of the closed figure to any other point on the boundary of the closed figure is less than or equal to a limit resolution size of human eyes.
