Abstract

A thin film transistor and a manufacturing method thereof, an array substrate and a manufacturing method thereof, and a display device are provided. The array substrate comprises: a base substrate and an electrode arranged on the base substrate. The electrode comprises: an aluminum layer or an aluminum alloy layer on the base substrate; and a first barrier layer arranged on the aluminum layer or the aluminum alloy layer and configured for preventing the aluminum layer or the aluminum alloy layer from producing hillocks. The array substrate can eliminate bad phenomenon that the metal aluminum or aluminum alloy formed on the base substrate produces hillocks when subjected to high temperature.
