An array substrate and a fabrication method thereof, and an electronic apparatus are disclosed. The array substrate includes a base substrate, a thin film transistor, a first connection electrode and a first insulation layer. The thin film transistor is on the base substrate and including a first electrode and a second electrode; the first connection electrode in a layer different from the first electrode and electrically connected with the first electrode; and the first insulation layer covering at least a portion of the first connection electrode; an area of an orthographic projection of the first connection electrode on the base substrate is larger than an area of an orthographic projection of the first electrode on the base substrate, and the first insulation layer is made from an organic insulation material.
