Dispersion liquid, composition, sealing member, light-emitting device, illumination tool, display device, and method for producing dispersion liquid

A method for producing a dispersion liquid, comprising:

• a first step of mixing at least a silane compound and water to obtain a hydrolysis liquid in which the silane compound is hydrolyzed;
• a second step of mixing the hydrolysis liquid and metal oxide particles to obtain a liquid mixture;
• a third step of dispersing the metal oxide particles in the liquid mixture to obtain a first dispersion liquid;
• and
• a fourth step of treating the metal oxide particles in the first dispersion liquid with a silicone compound to obtain a second dispersion liquid,
• wherein a content of the metal oxide particles in the liquid mixture is 10% by mass or more and 49% by mass or less, and a total content of the silane compound and the metal oxide particles in the liquid mixture is 65% by mass or more and 98% by mass or less.
