Title (EN) OPTICAL DEVICE
(FR) DISPOSITIF OPTIQUE
(JA) 光学デバイス
Abstract:
(EN) This optical device (1) comprises a first translucent substrate (10), a second translucent substrate (20) opposite the first substrate (10), and an optical control layer (30) disposed between the first substrate (10) and the second substrate (20) and having a first light-transmitting portion (31) including an optical medium (30a) and an irregular structure (30b) and a second light-transmitting portion (32) including, out of the optical medium (30a) and the irregular structure (30b),only the optical medium (30a). The optical medium (30a) and the irregular structure (30b) have mutually different refractive indexes. From a planar view, the first light-transmitting portion (31) and the second light-transmitting portion (32) are repeatedly disposed in one direction, and the surface area of the repeated portions of at least either the first light-transmitting portion (31) or the second light-transmitting portion (32) varies along the one direction.
(FR) L'invention concerne un dispositif optique (1) qui comprend un premier substrat translucide (10), un second substrat translucide (20) opposé au premier substrat (10), et une couche de commande optique (30) disposée entre le premier substrat (10) et le second substrat (20) et ayant une première partie de transmission de lumière (31) comprenant un milieu optique (30a) et une structure irrégulière (30b), et une seconde partie de transmission de lumière (32) comprenant, parmi le milieu optique (30a) et la structure irrégulière (30b), seulement le milieu optique (30a). Le milieu optique (30a) et la structure irrégulière (30b) ont des indices de réfraction mutuellement différents. Dans une vue en plan, la première partie de transmission de lumière (31) et la seconde partie de transmission de lumière (32) sont disposées de manière répétée dans une direction, et l'aire de surface des parties répétées d'au moins soit la première partie de transmission de lumière (31) soit la seconde partie de transmission de lumière (32) varie le long d'une direction.
(JA) 光学デバイス(1)は、透光性を有する第1基板(10)と、第1基板(10)に対向し、透光性を有する第2基板(20)と、第1基板(10)と第2基板(20)との間に配置され、光媒体(30a)及び凹凸構造(30b)を含む第1光透過部(31)と光媒体(30a)及び凹凸構造(30b)のうち光媒体(30a)のみを含む第2光透過部(32)とを有する光制御層(30)とを備え、光媒体(30a)と凹凸構造(30b)とは、屈折率が異なり、平面視において、第1光透過部(31)と第2光透過部(32)とは一の方向に向かって繰り返して配置されており、かつ、第1光透過部(31)及び第2光透過部(32)のうち少なくとも一方の繰り返し部分の面積が前記一の方向に沿って変化している。
