1. A display substrate, comprising:
at least two barrier layers in a peripheral area of the display substrate;
a second barrier layer in the peripheral area; and
at least one branch barrier connected to and extending away from the second barrier layer;
wherein the at least two barrier layers comprise:
a first barrier layer forming an enclosure; and
a third barrier layer on a side of the first barrier layer closer to a display area;
wherein the third barrier layer comprises one or more discontinuous portions;
wherein the third barrier layer comprises at least a first portion; and
the first portion is between a portion of the first barrier layer and the second barrier layer;
wherein a respective branch barrier comprises a first segment and a second segment; and
extension directions of the first segment and the second segment are different from each other;
wherein the third barrier layer comprises a first end segment and a first main segment; and
extension directions of the first end segment and the first main segment are different from each other;
wherein extension directions of the first segment and the first main segment are substantially parallel to each other; and
extension directions of the second segment and the first end segment are substantially parallel to each other;
wherein in plan view of the display substrate, an extension direction of the second segment is more toward the first main segment relative to an extension direction of the first segment; and
in plan view of the display substrate, an extension direction of the first end segment is more toward the first segment relative to an extension direction of the first main segment.
