1. A display panel, comprising a display substrate and a touch panel arranged on the display substrate, wherein
the display substrate comprises multiple sub-pixels, and at least one of the sub-pixels comprises an emitting region and a non-emitting region located on a periphery of the emitting region;
the touch panel comprises multiple touch electrodes, and at least one of the touch electrodes comprises multiple grid patterns enclosed by metal wires;
an orthographic projection of the emitting region on the display substrate is located within a range of that of a region enclosed by the metal wires on the display substrate;
an orthographic projection of the metal wire on the display substrate is located within a range of that of the non-emitting region on the display substrate;
at least one of the grid patterns comprises a first edge, second edge, third edge and fourth edge that form a ring;
the first edge and the third edge extend in a second direction, and the second edge and the fourth edge extend in a first direction, the first direction intersecting the second direction;
a shape of the grid pattern comprises at least one of a first curved ring, a second curved ring, a third curved ring, and a fourth curved ring;
a first edge and third edge of the first curved ring are curves curved towards a direction opposite to the first direction;
a first edge and third edge of the second curved ring are curves curved towards the first direction;
a second edge and fourth edge of the third curved ring are curves curved towards the second direction; and
a second edge and fourth edge of the fourth curved ring are curves curved towards a direction opposite to the second direction.
