View Patent ↗The invention provides a film forming method that improves throughput in a preliminary discharge. The film forming method according to the present invention can include a preliminary discharge step of preliminarily discharging liquid droplets from a head and a liquid droplet discharge step of relatively moving the head and the work to discharge the liquid droplets onto the surface of the work from the head. The preliminary discharge of the liquid droplets is carried out while the head and the work are moved relative to each other.
1. A film forming method, comprising:
preliminarily discharging liquid droplets from heads into a receiver for receiving functional liquid, wherein:
at least a portion of the preliminarily discharged liquid droplets are discharged from the heads directly into the receiver;
the receiver is formed in a ring-shape corresponding to a flat shape of a work; and
the receiver for receiving functional liquid is detached from the work; and
relatively moving the heads and the work to discharge the liquid droplets onto a surface of a work from the heads,
the preliminary discharge of the liquid droplets being carried out while the work is moved relative to the heads.
2. The film forming method according to claim 1 , in the liquid droplet discharge step, the preliminary discharge of the liquid droplets being carried out during acceleration of the heads and/or the work to a predetermined relative speed.
3. The film forming method according to claim 1 , the preliminary discharge of the liquid droplets being carried out in a liquid droplet reception area, a part of which is formed by the work.
4. The film forming method according to claim 1 , further comprising a vibrating step of, after liquid droplet discharge step, vibrating liquid within the heads to an extent that the liquid is not discharged from the heads.
5. A method of manufacturing a device, in which a film body is formed by discharging liquid droplets onto the surface of a work from heads, the film body being formed on the work using the film forming method according to claim 1 .
6. The method of manufacturing a device according to claim 5 , the work being a lens, and
the film body being a transmissive coating film for coating the lens.
7. The method of manufacturing a device according to claim 5 , the work being a substrate on which filter elements are arranged, and
the film body being an overcoat film for coating the filter elements.
8. The method of manufacturing a device according to claim 5 , the work being a substrate on which pixels including EL light-emitting layers are arranged, and
the film body being a counter electrode film formed at a predetermined place on the EL light-emitting layers.
9. The film forming method according to claim 1 , a circumferential edge portion of the work overlapping a portion of the receiver for receiving functional liquid.
10. The film forming method according to claim 1 , wherein the receiver for receiving functional liquid does not have the same compositions as that of the work.
