Abstract

The present disclosure provides a thin film transistor (TFT) array substrate, its manufacturing method and a display device. The method includes steps of: forming patterns of a common electrode, a common electrode line, a gate line and a data line on a substrate by a single patterning process; forming an insulating layer; forming a pattern of an active layer by a single patterning process; forming a gate insulating layer and forming via-holes corresponding to the gate line, the data line and the active layer in the gate insulating layer by a single patterning process; and forming patterns of a pixel electrode, a gate electrode, a source electrode and a drain electrode by a single patterning process.
