  • Droplet ejection apparatus, method for recovering droplet ejection head, method for forming thin film, and liquid crystal display
    Patent number: 7753474
    Abstract: A droplet ejection apparatus having a droplet ejection head, a cap casing, a pump, and a movement device is disclosed. The droplet ejection head ejects liquefied material containing functional material from nozzles as droplets. The cap casing has an accommodating portion in which a portion of the droplet ejection head including at least the nozzle forming surface is accommodated. The pump supplies liquid to the accommodating portion. The movement device moves at least one of the cap casing and the droplet ejection head relative with the other. When recovery is performed on the droplet ejection head or the droplet ejection head is held in a nonoperating state, the movement device arranges the cap casing relative to the droplet ejection head in such a manner that the nozzle forming surface is immersed in the liquid retained in the accommodating portion.
