1. A display substrate, comprising:
a base substrate, comprising an irregularly-shaped display region and a peripheral region surrounding the irregularly-shaped display region;
a plurality of rectangular pixels, disposed in the irregularly-shaped display region;
at least one irregularly-shaped pixel, disposed in the irregularly-shaped display region, wherein the at least one irregularly-shaped pixel is proximal to the peripheral region relative to the rectangular pixel, and a shape of a boundary line of a side, proximal to the peripheral region, of the each irregularly-shaped pixel matches with a shape of a boundary line of the irregularly-shaped display region; and
a black matrix layer, disposed on a side, distal from the base substrate, of the plurality of rectangular pixels and the at least one irregularly-shaped pixel, wherein an area of an opening formed by the black matrix layer in a region where each of the rectangular pixels is disposed is larger than an area of an opening formed by the black matrix layer in a region where any of the at least one irregularly-shaped pixel is disposed,
wherein the each irregularly-shaped pixel comprises a plurality of first sub-pixels, at least one of the first sub-pixels is an irregularly-shaped sub-pixel;
each irregularly-shaped sub-pixel comprises a pixel electrode and a compensation capacitor connected to the pixel electrode;
an orthographic projection of the pixel electrode on the base substrate is within an orthographic projection of the opening formed by the black matrix layer in the region where the first sub-pixel is disposed on the base substrate; and
an orthographic projection of the compensation capacitor on the base substrate is within a region outside the orthographic projection of the opening formed by the black matrix laver in the region where the irregularly-shaped sub-pixel is disposed on the base substrate, and is not overlapped with the orthographic projection of the pixel electrode on the base substrate.
