Abstract:
1. A method for manufacturing a thin-film transistor (TFT) array substrate, comprising steps of: providing a substrate; depositing a transparent conductive layer and a first metal layer in turn on the substrate, and patterning the transparent conductive layer and the first metal layer by a first multi-tone mask (MTM) to form a gate, a common electrode and a reflecting layer, wherein the gate comprises the transparent conductive layer and the first metal layer; the common electrode is formed by the transparent conductive layer; the reflecting layer is formed by the first metal layer on the common electrode; and the first MTM is a gray tone mask (GTM); depositing a gate insulation layer and a semiconductor layer on the substrate, and patterning the gate insulation layer and the semiconductor layer by a second MTM to remain the semiconductor layer on the gate; and depositing a second metal layer on the substrate, wherein the second metal layer is formed by stacking a second molybdenum metal layer, a second aluminum metal layer and a third molybdenum metal layer in turn, and patterning the second metal layer by a third MTM to form a source and a drain by the second metal layer on the remained semiconductor layer.
