Abstract
A thin film transistor array substrate includes a base substrate, a light shielding layer, a semiconductor layer, a gate insulating layer, a gate layer, and a source-drain metal layer in contact with the semiconductor layer and in contact with the light shielding layer sequentially disposed on the base substrate, a first insulating layer covering the source-drain metal layer disposed on the base substrate, and a metal protection layer disposed on the first insulating layer. The semiconductor layer, the gate layer, and the source-drain metal layer form a thin film transistor. An end of the metal protection layer is in contact with the source-drain metal layer, and another end of the metal protection layer is in contact with the light shielding layer.
