1. A display panel, comprising:
a substrate, comprising a display region and a non-display region at least partially surrounding the display region, wherein the display region comprises display pixels;
a light-shielding layer, in the non-display region and at least partially surrounding the display region;
a touch signal line, in the non-display region, at least partially surrounding the display region, wherein the light-shielding layer and the touch signal line are on a surface of and on a same side of the substrate, and the touch signal line is on a side of the light-shielding layer close to the display region in a direction parallel to the surface of the substrate, and configured to provide a touch signal to the display region; and
at least one light-shielding line, in the non-display region, at least partially surrounding the display region, wherein the light-shielding layer includes a portion which is on a side of all of the at least one light-shielding line and the touch signal line away from the display region in the direction parallel to the surface of the substrate; the at least one light-shielding line is arranged along a direction from the display region to the non-display region, an orthographic projection of a first part of the at least one light-shielding line on the substrate is overlapped with an orthographic projection of the light-shielding layer on the substrate, and an orthographic projection of a second part of the at least one light-shielding line on the substrate is between an edge of the orthographic projection of the light-shielding layer on the substrate close to the display region and an edge of the touch signal line away from the display region.
