Abstract

A method of manufacturing an electrooptical device includes forming a film-deposited section of function liquid droplets on a substrate by a liquid droplet ejection apparatus having a plurality of color-dependent function liquid droplet ejection heads are arranged such that a plurality of color-dependent partial imaging lines, each formed by a plurality of ejection nozzles, are formed so as to continuously make up a single imaging line in the Y-axis direction. An imaging process is performed by repeating a main scanning operation for driving each function liquid droplet ejection head in synchronization with moving of the substrate in the X-axis direction, and a sub-scanning operation for moving the function liquid droplet ejection heads through a carriage unit in the Y-axis direction by a length of a partial imaging line.

Claims (17)

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.

2. An electronic apparatus having incorporated therein an electrooptical device manufactured by the method of claim 1 .

3. An electrooptical device having a film-deposited section of function liquid droplets formed 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.

4. An electronic apparatus having incorporated therein an electrooptical device having incorporated therein an electrooptical device according to claim 2 .
