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 speckles and effectively avoiding deterioration in image quality due to a color change. [Solution] The particles include a first moiety 61 and a second moiety 62 that have different dielectric constants. A reflectance or a reflectance spectrum at a wavelength of invisible light, or a transmittance or a transmittance spectrum at a wavelength of invisible light is different between the first moiety 61 and the second moiety 62.
