Method of manufacturing display device, display device therefrom and manufacturing apparatus therefor
View Patent ↗A method of manufacturing a display device includes forming a thin film transistor on an insulating substrate, forming an electrode which is electrically connected with the thin film transistor, forming a wall which surrounds the electrode, supplying a first solvent to the electrode that is surrounded by the wall, and supplying ink which comprises an organic material and a second solvent to the electrode which has previously received the first solvent. Thus, the manufacturing method produces a display device which has a uniform organic layer.
1. A method of manufacturing a display device, comprising:
forming a thin film transistor on an insulating substrate;
forming an electrode which is electrically connected with the thin film transistor;
forming a wall which surrounds the electrode;
supplying a first solvent to the electrode which is surrounded by the wall; and
supplying ink which comprises an organic material and a second solvent to the electrode which has received the first solvent,
wherein the first solvent has a lower boiling point than the second solvent.
2. The method according to claim 1 , wherein the first solvent is supplied to at least one of a plurality of electrodes around the circumference of the electrode which receives the ink.
3. The method according to claim 1 , wherein the second solvent comprises a first sub-solvent which has a first boiling point and a second sub-solvent which has a second boiling point higher than the first boiling point, and
the first solvent and the first sub-solvent comprise substantially the same material.
4. The method according to claim 1 , wherein the ink is supplied along a plurality of sub-jetting regions which are provided in parallel with each other in a first direction and elongated in a second direction which is substantially perpendicular to the first direction.
5. The method according to claim 4 , wherein the first solvent is supplied along a sub-jetting region which is adjacent to the sub-jetting region wherein the ink is supplied.
6. The method according to claim 4 , wherein the ink is sequentially supplied in the first direction with respect to the plurality of sub jetting regions, and
the sub-jetting region along which the first solvent is supplied is ahead of the sub-jetting region along which the ink is supplied, along the first direction.
7. The method according to claim 4 , wherein the first solvent and the ink are supplied along the same sub-jetting region.
8. The method according to claim 4 , wherein the plurality of sub-jetting regions comprise a pair of external sub-jetting regions disposed opposite each other along the first direction, and an internal sub-jetting region which is disposed within the pair of external sub-jetting regions, and
a greater amount of the first solvent is supplied to the pair of external sub-jetting regions than to the internal sub-jetting regions.
9. The method according to claim 4 , wherein the plurality of sub-jetting regions comprise a pair of external sub-jetting regions disposed opposite each other along the first direction, and an internal sub-jetting region which is disposed within the pair of external sub-jetting regions, further comprising:
supplying the first solvent to the pair of external sub-jetting regions.
