Abstract
The present invention addresses the problem of providing a method for producing a phosphor dispersion liquid, which is not susceptible to settling of phosphor particles, without deteriorating the phosphor particles. In order to solve the above-mentioned problem, the present invention provides a method for producing a phosphor dispersion liquid that contains phosphor particles, laminar clay mineral particles, oxide microparticles and a solvent, said method comprising: a step of preparing a first dispersion liquid that has a viscosity of 50-500 mPa·s by mixing the laminar clay mineral particles, the oxide microparticles, and the solvent; and a step for mixing the phosphor particles into the first dispersion liquid.
