Method for discharging liquid body, method for manufacturing color filter, and method for manufacturing organic EL device
View Patent ↗A method for discharging a liquid body includes: discharging the liquid body to a discharged region from a plurality of nozzles while a plurality of droplet discharge heads having a nozzle line having the plurality of nozzles that discharge the liquid body as droplets and are arranged in a linear manner, and a substrate including a plurality of discharged regions having a nearly rectangular shape are relatively moved in a main scan direction that is nearly orthogonal to an arrangement direction of the droplet discharge heads. In the method, the plurality of discharged regions are composed of a first discharged region and a second discharged region. The first discharged region is disposed on the substrate to set a long side thereof along a certain direction, and the second discharged region has a smaller area than the first discharged region and is disposed to set a long side thereof nearly orthogonal to the long side of the first discharged region. Further, the first discharged region is disposed to set the long side thereof along the main scan direction in the discharging.
1. A method for discharging a liquid body, comprising:
arranging a first panel and a plurality of second panels on a substrate, the first panel including a plurality of first discharged regions each of which has a generally rectangular shape, each of the second panels including a plurality of second discharged regions each of which has a generally rectangular shape, each of the second panels being smaller than the first panel, each of the first discharged regions being disposed on the first panel to set a long side thereof along a prescribed direction, each of the second discharged regions having a smaller area than each of the first discharged regions and being disposed to set a long side thereof generally orthogonal to the long side of each of the first discharged regions, the first panel and the second panels being aligned along the prescribed direction and being arranged so as not to be aligned along a direction in which the long side of each of the second discharged regions extends, the second panels facing the first panel in the prescribed direction; and
discharging the liquid body to the first discharged regions and the second discharged regions from a plurality of nozzles while a plurality of droplet discharge heads, the heads having a nozzle line having the plurality of nozzles that discharge the liquid body as droplets and are arranged in a linear manner, and the substrate, are relatively moved in a main scan direction that is generally orthogonal to an arrangement direction of the droplet discharge heads,
each of the first discharged regions being disposed to set the long side thereof along the main scan direction in the discharging,
a discharge amount of the liquid body discharged from each of the plurality of nozzles with a single discharge being kept constant for the first discharged regions and the second discharged regions.
2. The method for discharging a liquid body according to claim 1 , wherein
at least two nozzles face a region, in a direction of a short side of each of the first discharged regions, of the first discharged regions.
3. The method for discharging a liquid body according to claim 1 , wherein
an arranging pitch between the droplets, the droplets being discharged from the nozzles and arranged in the first discharged regions, in the direction of a short side of each of the first discharged regions can be adjusted by disposing the nozzle line at an angle with the direction of the short side.
4. The method for discharging a liquid body according to claim 1 , wherein
in the discharging, the droplet discharge heads and the substrate are relatively moved in a sub scan direction that is generally orthogonal to the main scan direction in a plurality of relative moves between the droplet discharge heads and the substrate in the main scan direction.
5. A method for manufacturing a color filter, comprising:
discharging liquid bodies, the liquid bodies containing a colored layer forming material, of a plurality of colors to the first discharged regions and the second discharged regions by using the method for discharging a liquid body of claim 1 ; and
solidifying the liquid bodies being discharged so as to form colored layers of the plurality of colors on the substrate,
the second discharged regions having an arrangement direction orthogonal to that of the first discharged regions.
6. A method for manufacturing an organic electroluminescence (EL) device including a plurality of organic EL elements having functional layers having light emitting layers, in the first discharged regions and the second discharged regions, the method comprising:
discharging a liquid body containing a light emitting layer forming material in the first discharged regions and the second discharged regions on the substrate by using the method for discharging a liquid body of claim 1 ; and
solidifying the liquid body being discharged so as to form the light emitting layers,
the second discharged regions having an arrangement direction orthogonal to that of the first discharged regions.
