1. An array substrate, comprising:
a first substrate;
a switch layer group on one side of the first substrate, wherein the switch layer group comprises a plurality of switch units and a plurality of first shading layers; the plurality of first shading layers are spaced apart; and at least one first shading layer of the plurality of first shading layers is disposed on a same layer and of a same material as one layer in at least one switch unit of the plurality of switch units;
an insulating layer group on one side of the switch layer group away from the first substrate, wherein a plurality of first protrusions are provided on one surface of the insulating layer group away from the first substrate; a first connection part is connected between adjacent first protrusions, and a height, in a third direction, of a first protrusion of the adjacent first protrusions is higher than a height, in the third direction, of the first connection part; and an orthographic projection of the first protrusion and the first connection part on the first substrate is within an orthographic projection of the at least one first shading layer on the first substrate, the third direction being perpendicular to one surface of the first substrate close to the switch layer group; and
a reflective layer on one side of the insulating layer group away from the first substrate, wherein a plurality of second protrusions are provided on one surface of the reflective layer away from the first substrate; an orthographic projection of at least one first protrusion of the plurality of first protrusions on the first substrate is within an orthographic projection of at least one second protrusion of the plurality of second protrusions on the first substrate; and the reflective layer comprises a plurality of reflective parts, and the orthographic projection of the at least one first shading layer on the first substrate is within an orthographic projection of at least one reflective part of the plurality of reflective parts on the first substrate.
