1. An array substrate, comprising:

  • a base substrate; and

    a selective reflective layer on the base substrate;

    wherein the selective reflective layer comprises at least one selective reflective unit;

    the at least one selective reflective unit is configured to reflect light of a first wavelength range and transmit light of a second wavelength range,wherein the selective reflective units comprise a plurality of first dielectric layers and a plurality of second dielectric layers, which are alternately stacked, and the refractive index of the first dielectric layer is greater than the refractive index of the second dielectric layer, and the number of the first dielectric layers is larger than the number of the second dielectric layer by one.
