Embodiment Construction

[0027] Hereinafter, embodiments of a method of forming a predetermined pattern, a method of forming a colored layer, and a method of manufacturing an electro-optical device according to the present invention will be described with reference to the drawings.

[0028] [Liquid ejection device]

[0029] FIG. 1 is a perspective view showing a schematic configuration of a droplet ejection device IJ.

[0030] The droplet ejection device IJ includes a droplet ejection head 1 (droplet ejection unit), an X-axis direction drive shaft 4, a Y-axis direction guide shaft 5, a control device CONT, a table 7, a cleaning mechanism 8, and a base 9 , Heater 15.

[0031] In the following description, the X-axis direction is the scanning direction, and the Y-direction perpendicular to the X-axis direction is the non-scanning direction.

[0032] The table 7 supports a substrate P to be ejected with color filter ink, and includes a fixing mechanism (not shown) for fixing the substrate P at a refere...

Abstract

A forming method for a predetermined pattern, includes: measuring the radius of a droplet when the droplet is dropped onto a bank uprightly formed on a substrate; defining a target drop region of the droplet relative to a droplet disposition region delimited by the bank, based on the radius of the droplet; ejecting the droplet from a droplet ejecting section onto the target drop region; and forming the predetermined pattern onto the droplet disposition region.

Description

technical field [0001] The present invention relates to a method of forming a predetermined pattern, a method of forming a colored layer, and a method of manufacturing an electro-optical device. Background technique [0002] When manufacturing the color filter layer of a liquid crystal display device by a droplet ejection method (inkjet method), paint is continuously applied to each pixel surrounded by a partition wall (black matrix) called a bank. Droplets (ink). [0003] Specifically, partition walls (with a height of about 1 micron and hydrophobicity) are formed on the substrate, and color filter ink (hereinafter referred to as CF ink) is applied thereto by inkjet (hereinafter referred to as IJ application). [0004] However, if a large amount of ink is applied in order to achieve sufficient color density, there is a possibility that the ink overflows from the partition and gets mixed (color mixed) into adjacent pixels. [0005] In order to prevent the above disadvanta...
