1. A display panel, comprising:
a main display region and a sub display region, wherein:
the sub display region is surrounded by the main display region; the main display region adopts an active matrix driving manner, and the sub display region adopts a passive matrix driving manner;
the sub display region comprises a substrate, a first insulating layer, a first metal layer, a second insulating layer, a second metal layer, a dielectric layer, a third metal layer, and a flat layer stacked successively in order;
a signal line of the first metal layer is used to transmit a scan signal of the main display region, and a signal line of the third metal layer is used to transmit a display data signal of the sub display region; and
the second metal layer is used for isolating signal interference between the first metal layer and the third metal layer;
wherein an orthographic projection of the second metal layer on the substrate at least covers an orthographic projection of the signal line of the third metal layer on the substrate.
