Thin-film transistor substrate and method of manufacturing the same

摘要

A thin-film transistor substrate includes a gate line, and a gate electrode connected to the gate line, on a base substrate; an insulating layer on the gate electrode, the insulating layer including a first part and a second part, the first part having a hydrophobic property and the second part having a hydrophilic property; a data line extended in a different direction from the gate line, and a source electrode connected to the data line and on the second part of the insulating layer; a drain electrode on the second part of the insulating layer, the drain electrode spaced apart from the source electrode; a semi-conductor pattern overlapping the source electrode, the drain electrode and a gap between the spaced apart source and drain electrodes, where the semi-conductor pattern exposes the first part of the insulating layer; and a pixel electrode in contact with the drain electrode.
