1. A display substrate, comprising:
a base substrate;
a plurality of sub-pixels; each sub-pixel of the plurality of sub-pixels including a pixel electrode and an effective light-emitting region, the pixel electrode including a main body portion and a connection portion that are interconnected with each other; shapes of the main body portion and the effective light-emitting region being same, and a portion of a border of the main body portion forming at least partial border of the pixel electrode; the plurality of sub-pixels at least including a first sub-pixel and a second sub-pixel, a color of light emitted by the first sub-pixel and the second sub-pixel being same; and
a first insulating layer and a plurality of connection electrodes; the first insulating layer being located between all pixel electrodes of the plurality of sub-pixels and the plurality of connection electrodes and having a plurality of first via holes; a pixel electrode of the all pixel electrodes being correspondingly coupled to a connection electrode of the plurality of connection electrodes through a first via hole of the plurality of first via holes;
wherein areas of orthogonal projections of two pixel electrodes of the first sub-pixel and the second sub-pixel on the base substrate are unequal; and two orthogonal projections of a connection portion and a main body portion of at least one of the first sub-pixel or the second sub-pixel on a straight line extending in a first direction are at least partially non-overlapped;
an orthogonal projection of a pixel electrode of the second sub-pixel on a straight line extending in a second direction is located within an orthogonal projection of a pixel electrode of the first sub-pixel on the same straight line; and
the second direction intersects with the first direction, and an included angle between the second direction and the first direction is in a range from 80° to 100°;
wherein the sub-pixel further includes a pixel circuit, and all pixel circuits of the plurality of sub-pixels are arranged in the first direction to form rows and are arranged in the second direction to form columns, wherein
orthogonal projections of first via holes corresponding to a same row of pixel circuits on the base substrate are arranged along a first straight line; and
in sub-pixels corresponding to the same row of pixel circuits, effective light-emitting regions of first sub-pixels and effective light-emitting regions of second sub-pixels are respectively located at opposite sides of the first straight line.
