Problems solved by technology

However, in the case of forming a dummy area and only applying ink in the same manner as the display area, it may not be possible to sufficiently eliminate film thickness unevenness
That is to say, even if the ink is applied to the dummy area, the peripheral part of the display area tends to dry the solvent faster than the central part, and this method often cannot sufficiently avoid the occurrence of uneven film thickness.

Abstract

The objective is to provide a method of manufacturing an electro-optical device, capable of forming a pixel pattern, that has uniform film thickness. The method of manufacturing the electro-optical device, having a functional region 2a in which an electro-optical element functions at every pixel and a non-functional region 2b which is formed around the functional region 2a, comprises a discharge process of discharging liquid material, obtained by dissolving or dispersing functional material constituting the electro-optical element into a solvent onto a substrate by a liquid droplet discharge method. In the discharge process, the amount of solvent discharged to the non-functional region 2b per unit area is larger than the amount of the solvent discharged to the functional region 2a per unit area.

Description

technical field [0001] The present invention relates to a manufacturing method of a color filter substrate, a manufacturing method of an electro-optical device, an electro-optical device, and an electronic instrument. Background technique [0002] In recent years, an electro-optical device has been developed that uses a droplet discharge method in which functional materials such as organic fluorescent materials are ink-formed and the ink (composition) is discharged on a substrate to pattern the functional material. The method is an electro-optical device constructed by sandwiching a functional layer made of a functional material between a pair of opposite electrodes, especially an organic EL (electroluminescent) device using an organic light-emitting material as a functional material. [0003] As the patterning method of the above-mentioned functional material, the method adopted is: on the base material, a partition wall is formed around the pixel electrode made of ITO, and...
