1. A display panel, comprising a pixel layer, a support layer, a lens unit and a cover plate which are stacked in sequence, wherein:
the support layer is located on a light-emitting side of the pixel layer;
the lens unit comprises a lens layer, the lens layer comprises a lens area and a non-lens area, and the lens area comprises multiple lenses arranged in an array;
the display panel further comprises a polarization unit disposed on a light path between the pixel layer and the lens layer and configured to filter out light emitted from the pixel layer to the non-lens area;
the polarization unit comprises a first polarization layer and a second polarization layer, wherein the first polarization layer is closer to the pixel layer than the second polarization layer, and a transmission axis of the first polarization layer is perpendicular to a transmission axis of the second polarization layer;
the first polarization layer comprises a first wire grid polarizer, and the second polarization layer comprises a second wire grid polarizer;
wherein, the first wire grid polarizer comprises multiple parallel first protrusions arranged in a first direction;
the second wire grid polarizer comprises multiple parallel second protrusions arranged in a second direction; and
an area where the first protrusions are located and an area where the second protrusions are located correspond to the non-lens area, and the first direction is perpendicular to the second direction.
