An array substrate, a method for manufacturing the array substrate and a display device are provided. The array substrate includes: a base substrate, and a thin film transistor, a storage capacitor, and a lapping pattern for connecting the thin film transistor to the storage capacitor arranged on the base substrate; wherein the thin film transistor includes a semiconductor layer, a gate insulation layer, a gate electrode, an interlayer insulation layer, a source electrode and a drain electrode arranged sequentially in that order; the interlayer insulation layer includes at least two inorganic insulation layers and at least one organic insulation layer laminated one on another, and both a layer proximate to the base substrate and a layer distal to the base substrate in the interlayer insulation layer are the inorganic insulation layers.
