Display panel and display device

The display device, comprising a display panel, wherein:

• the display panel includes:
• a color film substrate and an array substrate configured opposite to each other;
• at least one light sensitive unit disposed at a side of the array substrate adjacent to the color film substrate;
• and collimating apertures penetrating a portion of film layers of the color film substrate and the array substrate along a first direction;
• wherein:
• the collimating apertures and the at least one light sensitive unit are disposed in a one-to-one correspondence;
• the first direction is perpendicular to the display panel;
• the color film substrate includes a first substrate, a first light-blocking layer, and at least one second light-blocking layer;
• the first light-blocking layer is disposed at a side of the first substrate adjacent to the array substrate, and includes a plurality of first openings;
• the at least one second light-blocking layer is disposed at a side of the first light- blocking layer adjacent to the array substrate, and includes a plurality of second openings;
• the array substrate includes a third light-blocking layer;
• the third light-blocking layer is disposed at a side of the array substrate adjacent to the color film substrate, and includes a plurality of third openings;
• and
• an orthographic projection of each of the plurality of first openings on the first substrate, an orthographic projection of a corresponding second opening of the plurality of second openings on the first substrate, and an orthographic projection of a corresponding third opening of the plurality of third openings on the first substrate, at least partially overlap an orthographic projection of a corresponding collimating aperture of the collimating apertures on the first substrate.
