Abstract

A thin film transistor array panel includes: a semiconductor layer disposed on an insulation substrate; a gate electrode overlapping the semiconductor layer; a source electrode and a drain electrode overlapping the semiconductor layer; a first barrier layer disposed between the source electrode and the semiconductor layer; and a second barrier layer disposed between the drain electrode and the semiconductor layer, wherein the first barrier layer and the second barrier layer include nickel-chromium (NiCr).
