Abstract:
(EN)
An optical sheet includes a plurality of particles and can maintain a speckle reducing effect over a long period of time. The optical sheet, which is used for a screen capable of displaying an image by light being shined thereon, is provided with a particle layer having an insulating liquid, a retention layer and a plurality of particles retained by the retention layer such that a rotary operation is possible. The particles include a first part and a second part and are retained by the retention layer such that the insulating liquid is present around the same, with the insulating liquid having a kinetic viscosity of 5.5 mm

Une feuille optique comprend une pluralité de particules et peut maintenir un effet de réduction de tavelure sur une longue période. La feuille optique, qui est utilisée pour un écran capable d'afficher une image par projection de lumière sur celui-ci, est pourvue d'une couche de particules ayant un liquide isolant, une couche de rétention et une pluralité de particules retenues par la couche de rétention de telle sorte qu'une opération de rotation est possible. Les particules comprennent une première partie et une seconde partie et sont retenues par la couche de rétention de telle sorte que le liquide isolant est présent autour de celle-ci, le liquide isolant ayant une viscosité cinétique inférieure ou égale à 5,5 mm
