1. A display panel, comprising:
a first substrate;
a first electrode layer disposed on the first substrate;
a second electrode layer disposed on a liquid crystal layer;
a second substrate disposed on the second electrode layer; and
a protective layer disposed on the second substrate,
wherein the display panel further comprises a light control layer, the light control layer is disposed between the first electrode layer and the second electrode layer, the light control layer comprises a first liquid crystal and light blocking layers, and the light blocking layers are disposed on a side of the light control layer close to the first electrode layer; and when no voltage is applied to the light control layer, the first liquid crystal is configured as an atomized liquid crystal for scattering light, and when a voltage is applied to the light control layer, the first liquid crystal is configured as a transparent liquid crystal, and the first liquid crystal comprises a polymer network liquid crystal material,
wherein the display panel further comprises:
