DISPLAY SUBSTRATE AND METHOD OF MANUFACTURING THE SAME

摘要

A thin film transistor substrate comprises: a gate metal pattern including a gate line extended in a first direction and a gate electrode electrically connected to the gate line; an active pattern overlapping the gate electrode; an etch-stop layer disposed on the active pattern; a data metal pattern including a data line extended in a second direction crossing the first direction, a source electrode electrically connected to the data line and electrically connected to the active pattern through a first through-hole formed in the etch-stop layer, and a drain electrode separated from the source electrode and electrically connected to the active pattern through a second through-hole adjacent to the first through-hole; and a first passivation layer disposed on the data metal pattern. According to embodiments of the present invention, masks used in manufacturing processes may be reduced.
