| 发明名称 | Phosphor dispersion liquid, and production method for LED device using same | ||
| 摘要 | The purpose is to provide a phosphor particle dispersion liquid in which the phosphor particles do not settle out when the phosphor dispersion liquid is left to stand. The phosphor dispersion liquid contains phosphor particles, clay mineral particles, inorganic particles, and a solvent. The phosphor dispersion liquid has viscosity η1 of 10 to 500 mPa·s at a shear rate of 1000 (1/s) at 25° C., and viscosity η2 of 1.0×103 to 1.0×105 mPa·s at a shear rate of 1 (1/s) at 25° C. | ||
