Claim 13:
14. A display panel, comprising: a substrate, an initialization signal line layer and a first auxiliary signal line layer sequentially stacked on the substrate along a direction away from the substrate; and a plurality of sub-pixel areas arranged in an array, wherein the plurality of sub-pixel areas form a plurality of rows of sub-pixel areas arranged in sequence along a second direction, each row of sub-pixel areas includes a plurality of sub-pixel areas arranged along a first direction, the first direction and the second direction intersect;
the initialization signal line layer includes an initialization signal line pattern arranged in each of the plurality of sub-pixel areas;
the first auxiliary signal line layer includes a plurality of first auxiliary signal line patterns corresponding to the plurality of sub-pixel areas in a one-to-one manner, and the first auxiliary signal line pattern is coupled to an initialization signal line pattern in a corresponding sub-pixel area, at least part of the first auxiliary signal line pattern extends along the first direction, and first auxiliary signal line patterns corresponding to sub-pixel areas in a same row of sub-pixel areas are sequentially coupled,
the display panel further includes a transistor structure, the initialization signal line pattern and an active layer in the transistor structure are arranged at a same layer,
wherein there is a third overlapping area between the orthographic projection of the first auxiliary signal line pattern on the substrate and the orthographic projection of the initialization signal line pattern on the substrate, the first auxiliary signal line pattern is directly coupled to the initialization signal line pattern through a via hole located in the third overlapping area,
wherein the first auxiliary signal line pattern includes a third portion and a fourth portion, the third portion extends along the first direction, in a direction perpendicular to the first direction, a width of the fourth portion is greater than a width of the third portion; there is the third overlapping area between an orthographic projection of the fourth portion on the substrate and the orthographic projection of the initialization signal line pattern on the substrate.
