Abstract:
1. A method of manufacturing an electrooptical device, comprising: forming a film-deposited section of function liquid droplets on a substrate by using a liquid droplet ejection apparatus for ejecting function liquid droplets so as to be landed in a plurality of pixel areas formed on the substrate on a basis of a color arrangement pattern composed of a plurality of colors, said function liquid droplets being ejected by moving, relative to the substrate, a plurality of color-dependent function liquid droplet ejection heads having a plurality of corresponding kinds of function liquids introduced therein, said apparatus including: a plurality of carriage units, each having the plurality of color-dependent function liquid droplet ejection heads placed on a corresponding carriage; an X-axis table having the substrate thereon and moving the substrate in an X-axis direction as a main scanning direction; a Y-axis table for moving each of the plurality of carriage units in the Y-axis direction; and control means for controlling each of the function liquid droplet ejection heads, the X-axis table, and the Y-axis table, wherein the plurality of color-dependent function liquid droplet ejection heads of each of the carriage units is arranged such that a plurality of color-dependent partial imaging lines, each formed by a plurality of ejection nozzles, are connected to one after another in a predetermined order in the Y-axis direction so as to make up a single divided imaging line, and wherein the control means performs the imaging process by repeating a main scanning operation for driving each of the function liquid droplet ejection heads in synchronization with the substrate moving in the X-axis direction and a sub-scanning operation for moving each of the function liquid droplet ejection heads in the Y-axis direction through the carriage unit by about each of the partial imaging lines.
