Abstract: front page image
(EN) [Problem] To provide an optical sheet, a screen, and a display device that are capable of sufficiently reducing speckle. [Solution] An optical sheet 50 comprising: a particle layer 55 that has a first side and a second side that are opposite to one another, said particle layer 55 having a retaining part 56 with cavities 56a therein, and having particles 60 that are housed within the cavities 56a, with said particles 60 each including a first polymer moiety 61 and a second polymer moiety 62; a first substrate 51 that is provided to the first side of the particle layer 55; a second substrate 52 that is provided to the second side of the particle layer 55; and a diffusion part 53, 58 that is provided to the second side of the particle layer 55.
(FR) L'invention fournit une feuille optique, un écran et un dispositif d'affichage qui permettent de réduire suffisamment un chatoiement. La feuille optique (50) est équipée : d'une couche de particules (55) qui possède un premier et un second côté s'opposant mutuellement, et qui possède une partie maintien (56) possédant à son tour une cavité (56a), et des particules (60) admises à l'intérieur de la cavité (56a), et contenant une première portion de polymère (61) et une seconde portion de polymère (62); d'un premier élément de base (51) qui est agencé d'un premier côté de la couche de particules (55); d'un second élément (52) qui est agencé d'un second côté de la couche de particules (55); et de parties diffusion (53, 58) agencées du second côté de la couche de particules (55).
(JA) 【課題】 スペックルを十分に低減することが可能な光学シート、スクリーン、及び表示装置を提供する。 【解決手段】 光学シート50は、互いに対向する第1の側及び第2の側を有する粒子層55であって、キャビティ56aを有する保持部56、及び、キャビティ56a内に収容され第1ポリマー部分61と第2ポリマー部分62を含む粒子60を有する粒子層55と、粒子層55の第1の側に設けられる第1基材51と、粒子層55の第2の側に設けられる第2基材52と、粒子層55の第2の側に設けられる拡散部53,58と、を備える。
