Display panel and display device

A display device, comprising a display panel, wherein the display panel comprises:

• a base substrate;
• an array layer located at one side of the base substrate;
• a display layer located at one side of the array layer facing away from the base substrate, wherein the display layer comprises a plurality of light-emitting elements;
• a color filter layer located at one side of the display layer facing away from the array layer, wherein the color filter layer comprises a first light-shielding layer and color resists, the first light-shielding layer comprises a plurality of first imaging pin-holes, and the color resists are disposed corresponding to the plurality of light-emitting elements;
• a touch layer located between the color filter layer and the display layer, wherein the first light-shielding layer shields the touch layer in a direction perpendicular to a plane where the base substrate is located;
• a second light-shielding layer located at one side of the display layer facing away from the color filter layer, wherein the second light-shielding layer comprises a plurality of second imaging pin-holes, and the plurality of second imaging pin-holes correspond to the plurality of first imaging pin-holes;
• and
• a light-sensing sensor layer, which is located at one side of the second light-shielding layer facing away from the display layer and is used for detecting images generated via the plurality of second imaging pin-holes;
• wherein a first imaging pin-hole of the plurality of first imaging pin-holes is larger than a second imaging pin-hole of the plurality of second imaging pin-holes, and a part of beams emitted by the light-emitting element serving as a pin-hole imaging light source are reflected by the touch layer adjacent to the first imaging pin-hole and then incident onto a region of the second light-shielding layer outside the second imaging pin-hole.
