1. A display substrate, comprising:
a base substrate;
a plurality of organic light-emitting elements on the base substrate, wherein each organic light-emitting element comprises a first electrode, a light-emitting layer and a second electrode which are sequentially stacked along a direction perpendicular to the base substrate, and the second electrode is on a side of the light-emitting layer facing the base substrate;
a data line, between the base substrate and the organic light-emitting element, and extending along a first direction; and
an electrode line, on the same layer as the data line and in a region outside a light-emitting region of the organic light-emitting element,
wherein the display substrate further comprises at least one connection portion, which is in the region outside the light-emitting region and is configured to connect the electrode line and the first electrode, the connection portion is spaced apart from the second electrode, and the light-emitting layer covers the second electrode and the at least one connection portion;
the display substrate further comprising:
a gate line, extending along the second direction and between the data line and the base substrate,
wherein the electrode line extends along the first direction, and a width of a portion of the electrode line overlapping the gate line is smaller than a width of a portion of the electrode line not overlapping the gate line.
