1. A display panel, comprising:
a substrate having a first surface and a second surface opposing the first surface in a Z-direction;
an array layer disposed on the first surface of the substrate;
a display layer disposed on a side of the array layer facing away from the substrate, wherein the display layer comprises light-emitting elements;
a color filter layer disposed on a side of the display layer facing away from the array layer, wherein the color filter layer comprises a light-blocking layer and color filters, wherein
the color filters are in correspondence with the light-emitting elements, and
the light-blocking layer comprises first light-blocking part and second light-blocking part, wherein at least one imaging aperture is disposed in the first light-blocking part, and the first light-blocking part is located between the second light-blocking part and the at least one imaging aperture;
a protective layer disposed on the color filter layer;
first metal part disposed on a side of the array layer facing away from the substrate, wherein a thickness of a portion of the first light-blocking part that overlaps the first metal part in the Z-direction is less than a thickness of a portion of the second light-blocking part that overlaps the first metal part in the Z-direction; and
an optical sensor layer disposed on a side of the color filter layer facing away from the protective layer and configured to detect light passing through the at least one imaging aperture.
