1. A display substrate, comprising:
a pixel-defining layer; and
sub-pixels of three colors;
wherein:
the pixel-defining layer defines a plurality of sub-pixel areas;
the sub-pixels are arranged in the plurality of sub-pixel areas;
the pixel-defining layer includes a first pixel-defining layer and a second pixel-defining layer;
a height of the second pixel-defining layer is smaller than a height of the first pixel-defining layer; and
the first pixel-defining layer is configured to separate adjacent sub-pixels of different colors;
the second pixel-defining layer is configured to separate adjacent sub-pixels of the same color; and
the sub-pixels of three colors include red sub-pixels, blue sub-pixels, and green sub-pixels;
the display substrate includes at least one column of sub-pixels, and in the at least one column of sub-pixels, sub-pixels belonging to a same column have a same color; and
in a column of sub-pixels of the same color, corresponding light-emitting layers of at least two adjacent sub-pixels are connected.
