1. An array substrate, comprising:
a substrate;
an active layer disposed on a side of the substrate and comprising a first active portion and a second active portion; and
a first insulating layer disposed on a side of the active layer away from the substrate and covering the active layer,
wherein the first active portion is formed with a first opening exposing the first insulating layer, the array substrate further comprises a second insulating layer and a third insulating layer, the second insulating layer and the third insulating layer are sequentially arranged on the first insulating layer, and the first opening extends through the second insulating layer and the third insulating layer,
wherein the array substrate further comprises a transparent conductive layer, the transparent conductive layer is disposed on the third insulating layer, the transparent conductive layer comprises a first transparent electrode, and the first transparent electrode covers the first opening,
wherein a surface of the first insulating layer away from the substrate comprises a first surface and a second surface, the first surface is a bottom surface of the first opening, the second surface surrounds the first surface, and the first surface is recessed relative to the second surface, and
wherein the first surface comprises a third surface and a fourth surface, the fourth surface surrounds the third surface, the second surface surrounds the fourth surface, the fourth surface is recessed relative to the third surface and the second surface, and the third surface is recessed relative to the second surface.
