Abstract

A thin film transistor substrate includes a thin film transistor including a gate electrode, a semiconductor layer, a source electrode and a drain electrode. Each of the source electrode and the drain electrode includes a wire layer and a protective layer. The protective layer includes zinc oxide in an amount greater than about 70% by weight and less than about 85% by weight and indium oxide in an amount greater than about 15% by weight and less than about 30% by weight.
