1. A display panel, comprising a plurality of pixel-driving circuits, wherein the display panel further comprises:
a base substrate;
a second conductive layer, located on a side of the base substrate, wherein the second conductive layer comprises first initial signal lines, and the first initial signal lines are configured to provide first initial signals to the pixel-driving circuits; and
a third conductive layer, located on a side of the second conductive layer distal to the base substrate, wherein the third conductive layer comprises second initial signal lines, and the second initial signal lines are configured to provide second initial signals to the pixel-driving circuits;
wherein, sheet resistance of a second conductive layer is greater than sheet resistance of the third conductive layer;
wherein an orthographic projection of at least a part of one of the first initial signal lines on the base substrate extends along a first direction;
an orthographic projection of at least a part of one of the second initial signal lines on the base substrate extends along a second direction, and the first direction and the second direction intersect;
the first initial signal lines are configured to provide the first initial signals to the plurality of pixel-driving circuits distributed along the first direction, respectively; and
the second initial signal lines are configured to provide the second initial signals to the plurality of pixel-driving circuits distributed along the second direction, respectively.
