Method of, and apparatus for, filling liquid droplet ejection head with function liquid; liquid droplet ejection apparatus; electrooptic device; method of manufacturing electrooptic device; and electronic apparatus

摘要

A function liquid is sent under pressure into the flow passages inside the liquid droplet ejection heads. Thereafter, the function liquid is sucked from nozzles of the liquid droplet ejection heads. In filling the liquid function droplet ejection heads with a function liquid, air bubbles in the flow passages inside the liquid droplet ejection heads can be efficiently discharged, whereby the liquid droplet ejection head is surely filled with the function liquid.
