Display panel and display device

A display panel, comprising a driving circuit arranged on a base substrate and a signal line configured to provide a signal to the driving circuit,

• wherein the signal line comprises at least two main signal sub-lines, each main signal sub-line comprises a first end and a second end,
• the first ends of the at least two main signal sub-lines are electrically coupled to each other, and the second ends of the at least two main signal sub-lines are electrically coupled to each other;
• N main signal sub-lines in the at least two main signal sub-lines are directly electrically coupled to the driving circuit, and configured to provide the signal to the driving circuit;
• and
• each of the N main signal sub-lines is a direct-coupled main signal sub-line, and a main signal sub-line in the at least two main signal sub-lines other than the direct-coupled main signal sub-lines is an indirect-coupled main signal sub-line,
• wherein N is a positive integer and smaller than the quantity of the main signal sub-lines in the signal line;
• wherein the quantity of main signal sub-lines in the signal line is A, the signal line further comprises M auxiliary signal sub-lines, and an ath main signal sub-line corresponds to an mth auxiliary signal sub-line, wherein A is an integer greater than 1, M is a positive integer, a is a positive integer smaller than or equal to A, and m is a positive integer smaller than or equal to M,
• wherein the ath main signal sub-line is electrically coupled to the mth auxiliary signal sub-line through at least two connection via-holes, the ath main signal sub-line and the mth auxiliary signal sub-line are arranged at different conductive layers, and an orthogonal projection of the ath main signal sub-line onto the base substrate at least partially overlaps an orthogonal projection of the mth auxiliary signal sub-line onto the base substrate;
• wherein each auxiliary signal sub-line comprises a plurality of auxiliary line portions electrically coupled to a corresponding main signal sub-line through at least two via-holes, and an orthogonal projection of each auxiliary line portion onto the base substrate is located within an orthogonal projection of the corresponding main signal sub-line onto the base substrate.
