1. A display panel, comprising:
an anti-reflection film located at a light-exiting side of the display panel,
wherein a reflectivity of the anti-reflection film for light having a first wavelength is smaller than a reflectivity of the anti-reflection film for light having a second wavelength, the first wavelength is different from the second wavelength, the light having the first wavelength is any one of light in ambient light outside the display panel, and the light having the second wavelength is light emitted by a first fingerprint recognition light source located inside the display panel; and
the light having the second wavelength reflected by a first surface of the anti-reflection film and the light having the second wavelength reflected by a second surface of the anti-reflection film do not satisfy interference cancellation condition, the first surface being opposite to the second surface; and/or
the first wavelength λ1 satisfies: 400 nm<λ1<700 nm; and the second wavelength λ2 satisfies: λ2≥700 nm, or λ2≤400 nm.
