Abstract:
1. A thin film transistor substrate, comprising: a substrate; and a plurality of thin film transistors disposed on the substrate, wherein each of the thin film transistors comprises: a gate electrode disposed on the substrate; a first diffusion barrier layer disposed on the substrate and covering the gate electrode; a gate insulating layer disposed on the first diffusion barrier layer, wherein the gate insulating layer comprises a first film layer and a second film layer disposed on the first film layer, wherein the first film layer covers the first diffusion barrier layer, the hydrogen content of the second film layer is less than that of the first film layer, and the hydrogen content of the second film layer is less than or equal to about 20 atomic percent and more than 0 atomic percent; an active layer disposed on the gate insulating layer and over the gate electrode; a source electrode disposed on the substrate and electrically connected to the active layer; a drain electrode disposed on the substrate and electrically connected to the active layer; and a protective layer covering the source electrode and the drain electrode.
