1. An inkjet printing device comprising:
an alignment plate;
a substrate positioned on one surface of the alignment plate in a third direction; and
an inkjet head disposed on the substrate,
wherein the alignment plate includes a plurality of position adjustors having a first position adjustor positioned on a first side surface of the alignment plate in a first direction; and
a second position adjustor, a third position adjustor, a fourth position adjustor, a fifth position adjustor, and a sixth position adjustor positioned at a second side surface of the alignment plate in a second direction perpendicular to the first direction, and
each of the position adjustors individually adjusts a position of the substrate,
wherein each of the plurality of position adjustors is connected to a ball that is in contact with the substrate.
 
2. A inkjet printing device comprising:
an alignment plate;
a substrate positioned on one surface of the alignment plate in a third direction; and
an inkjet head disposed on the substrate,
wherein the alignment plate includes a plurality of position adjustors having a first position adjustor positioned on a first side surface of the alignment plate in a first direction; and
a second position adjustor, a third position adjustor, a fourth position adjustor, a fifth position adjustor, and a sixth position adjustor positioned at a second side surface of the alignment plate in a second direction perpendicular to the first direction;
each of the position adjustors individually adjusts a position of the substrate;
a first ball directly connected to the first position adjustor and in contact with a first side surface of the substrate;
a second ball directly connected to the second position adjustor and in contact with a second side surface of the substrate; and
a third ball directly connected to the third position adjustor and in contact with the second side surface of the substrate,
wherein motion directions of the first position adjustor, the second position adjustor, and the third position adjustor are equal to motion directions of the first ball, the second ball, and the third ball.
 
12. An inkjet printing device comprising:
a plurality of inkjet printing units overlapping in a third direction,
wherein each inkjet printing unit includes:
an alignment plate;
a substrate positioned on one surface of the alignment plate in the third direction; and
an inkjet head disposed on the substrate,
wherein the alignment plate includes a plurality of position adjustors having a first position adjustor positioned at a first side surface of the alignment plate in a first direction perpendicular to the third direction, and a second position adjustor, a third position adjustor, a fourth position adjustor, a fifth position adjustor, and a sixth position adjustor positioned as a second side surface of the alignment plate in a second direction perpendicular to the first direction and third direction, and
each of the position adjustors adjusts position of the substrate,
wherein each of the plurality of position adjustors is connected to a ball that is in contact with the substrate.
