Abstract
The present invention provides a phosphor dispersion liquid in which phosphor particles, laminar clay mineral microparticles, and oxide microparticles are dispersed in a solvent, wherein when a glass bottle of a 15-mm inner diameter is filled with 5 ml of the phosphor dispersion liquid and left standing, the time taken for a supernatant layer to be generated due to settling of the phosphor particles is four hours or longer.
Claims6
A phosphor dispersion liquid comprising a dispersion solvent, phosphor particles, laminar clay mineral microparticles, and oxide microparticles, the phosphor particles, the laminar clay mineral microparticles, and the oxide microparticles being dispersed in the dispersion solvent, wherein
- the laminar clay mineral microparticles have a plate shape, and
- when 5 ml of the phosphor dispersion liquid is charged into a glass bottle of 15 mm inner diameter and allowed to stand, the time it takes for a supernatant layer to be generated due to settling of the phosphor particles is 4 hours or longer.
