Abstract

The color filter substrate has a functional region which includes a plurality of colored layers and which functions as a color filter selectively transmitting predetermined color light components and a non-functional region other than the functional region. The method includes discharging, onto a substrate, a liquid material, in which coloring materials constituting the colored layers are dissolved or dispersed into a solvent, with a liquid droplet discharge method. In the discharging of the liquid material, the liquid material is discharged onto the functional region and the liquid material or the solvent is discharged onto the non-functional region. The amount of the solvent discharged onto the non-functional region per unit area is larger than the amount of the solvent discharged onto the functional region per unit area.

Claims (10)

1. A method of manufacturing an electro-optical device which has a functional region in which electro-optical elements of pixels function and a non-functional region which is formed around the functional region, the method comprising:

forming liquid holding regions in the functional region and in the non-functional region, an area of the liquid holding region in the functional region being formed larger than an area of the liquid holding region in the non-functional region:

discharging, into the liquid holding region in the functional region and in the non-functional region, a liquid material, in which functional materials constituting the electro-optical elements are dissolved or dispersed into a solvent, with a liquid droplet discharge method,

wherein, in the discharging of the liquid material, the liquid material is discharged onto the functional region and the liquid material or the solvent is discharged onto the non-functional region, and

the amount of the solvent discharged onto the non-functional region per unit area is larger than the amount of the solvent discharged onto the functional region per unit area.

2. The method of manufacturing an electro-optical device according to claim 1 ,

wherein the functional region is rectangular in plan view and a density of the liquid holding region in the non-functional region is different in the longitudinal and traverse directions of the functional region.

3. The method of manufacturing an electro-optical device according to claim 1 ,

wherein the functional region is rectangular in plan view and the non-functional region includes a first non-functional region formed in a traverse direction of the functional region and a second non-functional region formed in a longitudinal direction of the functional region, wherein in the discharging of the liquid material, the amount of the solvent discharged onto the first non-functional region per unit area is larger than the amount of the solvent discharged onto the second non-functional region per unit area.

4. The method of manufacturing an electro-optical device according to claim 1 , further comprising: forming the liquid holding region of the non-functional region in a substantially rectangular shape along a side of the functional region.
