摘要

[Problem] To provide particles, an optical sheet, a screen, a display device, a particle inspection device, a particle manufacturing device, a particle inspection method, a particle manufacturing method, a screen inspection method, and a screen manufacturing method that are capable of reducing speckle and effectively avoiding image quality degradation associated with color change. [Solution] The particles include a first moiety 61 and a second moiety 62 that have different dielectric constants. The first moiety 61 and the second moiety 62 have different reflectance spectra or different reflectances of non-visible light wavelengths, or else have different transmittance spectra or different transmittances of non-visible light wavelengths.
