1. A display panel, comprising:
a flexible display substrate;
a circuit board on a back side of the flexible display substrate, wherein the circuit board is bonded and connected to the flexible display substrate, and is provided with a circuit device on a back side of the circuit board away from the flexible display substrate; and
an auxiliary bending protection structure on the back side of the flexible display substrate, wherein the auxiliary bending protection structure is fixedly connected to the back side of the flexible display substrate, and the circuit device is in a region where the auxiliary bending protection structure is located,
wherein the auxiliary bending protection structure comprises a flexible backing and a structural member;
the flexible backing is fixedly arranged on the back side of the flexible display substrate; the flexible backing has a first hollow therein, and the circuit board is exposed at the first hollow; and
the structural member is on a side of the flexible backing away from the flexible display substrate, and is fixedly connected to the flexible backing; and the circuit device is in a region where the structural member is located.
