Abstract
An array substrate includes a first substrate, a switch layer group, an insulation layer group and a reflective layer. The switch layer group includes switch units and first shading layers, the first shading layers being spaced apart, the first shading layer being disposed on a same layer and of a same material as one layer in the switch unit. The insulating layer group is provided with a plurality of first protrusions on a surface away from the first substrate. The reflective layer is provided with a plurality of second protrusions on a surface away from the first substrate. An orthographic projection of the first protrusion on the first substrate is within an orthographic projection of the second protrusion on the first substrate, and an orthographic projection of the first shading layer on the first substrate is within an orthographic projection of the reflective layer on the first substrate.
