Abstract

The present disclosure provides a TFT, an array substrate, their manufacturing methods, and a display device. A source electrode and a drain electrode of the TFT are each of a multi-layered structure including a metal layer and a metal barrier layer. An a-Si active layer of the TFT is covered with an etch stop layer, via-holes penetrating through the etch stop layer are provided at positions corresponding to the source electrode and the drain, and the source electrode and the drain electrode are connected to the a-Si active layer through the via-holes.
