Abstract

An array substrate, a manufacturing method thereof and a display device are provided. The array substrate includes: a base substrate; a first electrode located on the base substrate and including a pad portion, the pad portion including a first surface and a second surface, the second surface being closer to the base substrate than the first surface; a first insulation layer located on the first electrode and including a first via hole; a second insulation layer located on the first insulation layer and including a second via hole; and a second electrode located on the second insulation layer; the second electrode is electrically connected with the first electrode at the pad portion through the first via hole and the second via hole, and an orthographic projection of the pad portion on the base substrate falls within an orthographic projection of the second via hole on the base substrate.
