Patent ID: 8794180

Claim:
An ejection device that ejects a spacer dispersion liquid prepared by dispersing spacers in a solvent, and disposes droplets of the spacer dispersion liquid on spacer regions of a substrate, the ejection device comprising: a multi-nozzle mechanism that comprises a pair of nozzle row units prepared by equally dividing a nozzle row that comprises a plurality of nozzles that are aligned so as to face different spacer regions and are configured to eject the spacer dispersion liquid; a moving mechanism configured to move the multi-nozzle mechanism with respect to the substrate in a longitudinal direction of the spacer regions so that the nozzles are translationally moved along the spacer regions and move the multi-nozzle mechanism with respect to the substrate in an align direction of the spacer regions so that the spacer regions that face the nozzles are changed; and a control mechanism configured to give a command to the moving mechanism to move the multi-nozzle mechanism in the align direction by a length of the nozzle row unit each time the multi-nozzle mechanism turns around when performing forward and backward movements in the longitudinal direction, in a forward path, give a command to the nozzles to eject the spacer dispersion liquid in a cycle such that the droplets are disposed at given intervals on the spacer regions, and in a backward path, give a command to the nozzles to eject the spacer dispersion liquid in a cycle that is the same as the cycle in the forward path so that the droplets are disposed between adjacent droplets that are disposed on the spacer regions in the forward path, wherein when one of the pair of nozzle row units includes a failure nozzle, the control mechanism gives a command to the failure nozzle not to eject the spacer dispersion liquid, and gives a command to a nozzle in the other nozzle row unit in a position that corresponds to a position of the failure nozzle to halve the cycle in the forward path and the cycle in the backward path.
