Abstract
A thin film transistor substrate that has reduced production cost and defect rate is presented. The thin film transistor substrate includes a gate wiring line formed on an insulating substrate and including a gate electrode, a data wiring line formed on the gate wiring line and including a source electrode and a drain electrode, a passivation layer pattern formed on parts of the data wiring line other than the drain electrode and a pixel region, and a pixel electrode electrically connected to the drain electrode. The pixel electrode includes zinc oxide.
