Pattern film formation method and organic EL device manufacturing method

1. A pattern film formation method comprising:

discharging liquid from at least one first discharge head toward a first pattern film formation region on a substrate; and

discharging liquid from a plurality of second discharge heads toward a second pattern film formation region that is narrower than the first pattern film formation region,

a number of the second discharge heads being greater than a number of the at least one first discharge head.

2. The pattern film formation method according to claim 1 , further comprising

moving one of the substrate and the at least one first discharge head relative to the other of the substrate and the at least one first discharge head in a first direction, and

moving one of the substrate and the second discharge heads relative to the other of the substrate and the second discharge heads in a second direction.

3. The pattern film formation method according to claim 2 , wherein

the second direction is a direction along which the second discharge heads are aligned.

4. The pattern film formation method according to claim 2 , wherein

the number of the second discharge heads is equal to or greater than a nth multiple of the number of the at least one first discharge head when a length of the second pattern film formation region with respect to the second direction is 1/n of a length of the first pattern film formation region with respect to the first direction.

5. The pattern film formation method according to claim 3 , wherein

the number of the second discharge heads is equal to or greater than a nth multiple of the number of the at least one first discharge head when a length of the second pattern film formation region with respect to the second direction is 1/n of a length of the first pattern film formation region with respect to the first direction.

6. An organic EL device manufacturing method comprising:

discharging liquid having a first color from at least one first discharge head toward a first pattern film formation region on a substrate; and

discharging liquid having a second color from a plurality of second discharge heads toward a second pattern film formation region that is narrower than the first pattern film formation region,

a number of the second discharge heads being greater than a number of the at least one first discharge head.

7. The organic EL device manufacturing method according to claim 6 , further comprising

moving one of the substrate and the at least one first discharge head relative to the other of the substrate and the at least one first discharge head in a first direction, and

moving one of the substrate and the second discharge heads relative to the other of the substrate and the second discharge heads in a second direction.

8. The organic EL device manufacturing method according to claim 7 , wherein

the second direction is a direction along which the second discharge heads are aligned.

9. The organic EL device manufacturing method according to claim 7 , wherein

the number of the second discharge heads is equal to or greater than a nth multiple of the number of the at least one first discharge head when a length of the second pattern film formation region with respect to the second direction is 1/n of a length of the first pattern film formation region with respect to the first direction.

10. The organic EL device manufacturing method according to claim 8 , wherein

the number of the second discharge heads is equal to or greater than a nth multiple of the number of the at least one first discharge head when a length of the second pattern film formation region with respect to the second direction is 1/n of a length of the first pattern film formation region with respect to the first direction.
