Abstract
A thin film transistor substrate can include a thin film transistor on a base substrate, and a capacitor connected to the thin film transistor. The thin film transistor can include an active layer on the base substrate, and a gate electrode spaced apart from the active layer to at least partially overlap the active layer. The capacitor can include a first capacitor electrode disposed on a same layer as the active layer of the thin film transistor, and a second capacitor electrode disposed on a same layer as the gate electrode and overlapping with the first capacitor electrode. The first capacitor electrode can include an active material layer made of a same material as the active layer of the thin film transistor, and a metal-containing layer disposed on the active material layer. The metal-containing layer can include a metal different than the active material layer and can absorb hydrogen.
