A thin-film transistor substrate and a display device comprising the same are provided which can improve display quality by reducing or preventing deterioration of the characteristics of thin-film transistors. The thin-film transistor substrate comprises thin-film transistors on a lower protective metal layer. Each thin-film transistor comprises a buffer layer, a semiconductor layer, a first insulating film, a gate electrode, a second insulating film, a source electrode and a drain electrode, and a first electrode. The lower protective metal layer is electrically connected to the gate electrode and overlaps the channel region of the semiconductor layer.

Thin-film transistor substrate and display device comprising the same

A thin film transistor array substrate having excellent characteristics and a method for manufacturing the same are disclosed. The thin film transistor array substrate includes a substrate, a gate electrode positioned on the substrate, a gate insulating layer positioned on the gate electrode, an active layer which is positioned on the gate insulating layer and includes a channel, an ohmic contact layer positioned on the active layer, and a source electrode and a drain electrode which are respectively connected to both sides of the active layer through the ohmic contact layer. The gate insulating layer includes a phosphorus-doped layer positioned adjacent to the active layer.
