An object of the present invention is to provide a method for producing a wavelength conversion substrate. Through the production method, when the wavelength conversion substrate is produced by filling a plurality of regions defined by light-shielding partition walls with a plurality of different types of wavelength conversion materials, mixing of different kinds of materials among the wavelengthconversion materials filled in the aforementioned regions can be suppressed. In the solution of the present invention, when an inkjet method is used to produce the wavelength conversion substrate by filling the wavelength conversion materials containing quantum dots in a predetermined region defined by the light-shielding partition walls in the wavelength conversion substrate, after the photosensitive composition containing the quantum dots is injected into the predetermined region, only the photosensitive composition that has been injected into the predetermined region is selectively exposedand cured, and then a clea
