Method for producing composition for forming wavelength conversion member, color resist, color fil

An object of the present invention is used to produce a wavelength conversion member, and when the wavelength conversion member is irradiated with light, the wavelength conversion efficiency of light is easily increased, and the storage stability is not impaired It is to provide a composition for forming a wavelength conversion member. The composition for forming the wavelength conversion member contains a photopolymerizable compound (A), a photopolymerization initiator (B), a phosphor (C), a rare earth phosphate particle (D1), and a rare earth titanate particle (D 2 ) that is at least one of the [Selection drawing]Fig. 1
