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.
