FUNCTIONAL INK, FILM FORMATION METHOD, DROPLET EJECTION APPARATUS, DEVICE WITH FILM AFFIXED THERETO, AND ELECTRONIC APPLIANCE

摘要

Provided are: a functional ink which, when passing through a supply line, is less apt to suffer turbulence; a film formation method and a droplet ejection apparatus both using the functional ink; a device with a film affixed thereto and produced using the method and apparatus; and an electronic appliance including this device with a film affixed thereto. This functional ink is characterized by: comprising a film-forming material and a liquid medium in which the film-forming material has been dissolved or dispersed; having a coefficient of dynamic viscosity at room temperature of 2.5×10-7 to 235×10-7 m2/s; and having been regulated so as to have a Reynolds number, when passing through the supply line at room temperature, of 2,300 or less.
