METHOD FOR FILLING FUNCTIONAL LIQUID DROPLET EJECTION HEAD WITH FUNCTIONAL LIQUID, FUNCTIONAL LIQUID SUPPLYING DEVICE AND LIQUID DROPLET EJECTION APPARATUS FOR MANUFACTURING ELECTRO-OPTICAL APPARATUS, AND ELECTRO-OPTICAL APPARATUS

摘要

Provided herein is a method for filling a functional liquid droplet ejection head with functional liquid. The method includes: initially filling functional liquid channels and intrahead channels included in the functional liquid droplet ejection head with a functional liquid by introducing functional liquid from a functional liquid tank through the functional liquid channels to the functional liquid droplet ejection head used in an inkjet mode; and passing cleaning liquid into the functional liquid channels and the intrahead channel included in the functional liquid droplet ejection head prior to the initially filling.
