Printing method

1. An inkjet printing method comprising:

moving an inkjet head to discharge ink to a substrate including printing row areas;

discharging ink to a first printing row area and a second printing row area among the printing row areas;

discharging ink to a third printing row area among the printing row areas and the second printing row area; and

discharging ink only to the first printing row area, wherein

the ink contains at least a wavelength converting particle and a light scattering element.

2. The inkjet printing method of claim 1 , further comprising:

discharging ink to an n−1 th printing row area and an n th printing row area among the printing row areas, wherein n is an integer greater than 3.

3. The inkjet printing method of claim 2 , further comprising:

discharging ink only to the n th printing row area after the discharging of the ink to the n−1 th printing row area and the n th printing row area.

4. The inkjet printing method of claim 3 , wherein

the ink is discharged to the n−1 th printing row area through a first head of the inkjet head, and

the ink is discharged to the n th printing row area through a second head of the inkjet head.

5. The inkjet printing method of claim 3 , wherein in case that the ink is discharged only to the n th printing row area,

the ink is discharged only through a first head of the inkjet head, and

the ink is not discharged through a second head of the inkjet head.

6. The inkjet printing method of claim 5 , wherein in case that the ink is discharged only to the first printing row area,

the ink is discharged only through the first head of the inkjet head.

7. An inkjet printing method comprising:

moving an inkjet head to discharge ink to a substrate including printing row areas;

discharging ink to a first printing row area and a second printing row area among the printing row areas;

discharging ink to a third printing row area among the printing row areas and the second printing row area;

discharging ink only to the first printing row area;

forming a first color filter, a second color filter, and a third color filter on the substrate; and

forming a partition wall on the first color filter, the second color filter, and the third color filter, the partition wall including openings.

8. The inkjet printing method of claim 7 , wherein

the openings include a first opening, a second opening, and a third opening, and

at least one of the openings is formed in at least one printing row area among the printing row areas.

9. The inkjet printing method of claim 8 , wherein the openings are repeatedly arranged in the printing row areas.

10. The inkjet printing method of claim 8 , wherein

the inkjet head includes a blue ink printing head, a red ink printing head, and a green ink printing head,

the blue ink printing head discharges ink to the second opening,

the green ink printing head discharges ink to the third opening, and

the red ink printing head discharges ink to the first opening.

11. The inkjet printing method of claim 10 , wherein the ink discharged to the openings includes particles.

12. The inkjet printing method of claim 11 , wherein the particles include at least one of a wavelength converting particle and a scattering element.

13. The inkjet printing method of claim 12 , wherein the blue ink printing head discharges ink including the scattering element.

14. The inkjet printing method of claim 12 , wherein each of the green ink printing head and the red ink printing head discharges ink including the wavelength converting particle and the scattering element.

15. The inkjet printing method of claim 12 , wherein the scattering element includes titanium oxide.

16. The inkjet printing method of claim 12 , wherein the wavelength converting particle includes a quantum dot.
