Abstract
A method of forming a conductive pattern includes forming a trench on a substrate, and providing a conductive ink to the trench while an electric field is generated between the substrate and a nozzle which ejects the conductive ink.
Claims9
A method of manufacturing a display substrate, the method comprising:
- forming a second signal line and a gate electrode and then providing a semiconductor pattern on a substrate, wherein the gate electrode is connected to the second signal line, and the semiconductor pattern overlaps the gate electrode;
- providing a source electrode and a drain electrode on the substrate on which the semiconductor pattern provided, wherein each of the source electrode and the drain electrode overlap the semiconductor pattern;
- forming a trench on the substrate;
- forming a first signal line by providing the trench with a conductive ink while an electric field is generated between the substrate and a nozzle, wherein the nozzle ejects the conductive ink,
- wherein the second signal line crosses the first signal line;
- and
- providing a pixel electrode on the substrate on which the first signal line and the second signal line are provided,
- wherein the electric field is generated by applying different voltages to the substrate and the nozzle, respectively, and
- wherein the forming the trench on the substrate comprises:
- providing an organic layer on the substrate, on which the source electrode and the drain electrode are provided;
- and
- forming the trench and a hole on the organic layer by patterning the organic layer, wherein the trench exposes the source electrode and the hole exposes the drain electrode.
