Abstract

A pattern film formation method includes: discharging liquid from at least one first nozzle toward a first pattern film formation region on a substrate; and discharging liquid from a plurality of second nozzles toward a second pattern film formation region that is narrower than the first pattern film formation region. A number of the second nozzles is greater than a number of the at least one first nozzle.

Claims (18)

1. A pattern film formation method comprising:

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

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

a number of the second nozzles being greater than a number of the at least one first nozzle.

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

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

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

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

the first direction is the same direction as the second direction.

4. An organic EL device manufacturing method comprising:

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

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

a number of the second nozzles being greater than a number of the at least one first nozzle.

5. The organic EL device manufacturing method according to claim 4 , further comprising

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

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

6. The organic EL device manufacturing method according to claim 5 , wherein

the first direction is the same direction as the second direction.
