Abstract:
(EN) An optical device (1) is provided with: a translucent first electrode layer (40) and second electrode layer (50) disposed facing each other; and a light-distribution layer (30) for distributing incident light, the light-distribution layer (30) being disposed between the first electrode layer (40) and the second electrode layer (50); the light-distribution layer (30) including an uneven-structure layer (31) having a plurality of protrusions (33) arranged in a first direction, and a variable-refractive-index layer (32) which is disposed so as to fill spaces between the plurality of protrusions (33) and in which the refractive index thereof varies in accordance with a voltage applied between the first electrode layer (40) and the second electrode layer (50), the first electrode layer (40) and/or the second electrode layer (50) being formed from a plurality of electrode pieces, the plurality of electrode pieces including a plurality of first electrode pieces (51) to which a first potential is applied and a plurality of second electrode pieces (52) to which a second potential is applied, and the plurality of first electrode pieces (51) and the plurality of second electrode pieces (52) being arranged in alternating fashion in the first direction.
(FR) Le dispositif optique (1) de l’invention est équipé : d’une première ainsi que d’une seconde couche d’électrode (40, 50) dotées de propriétés translucides, et disposées en opposition l’une par rapport à l’autre ; et d’une couche de répartition lumineuse (30) qui est disposée entre la première et la seconde couche d’électrode (40, 50), et qui répartit une lumière incidente. La couche de répartition lumineuse (30) contient : une couche de structure en creux et reliefs (31) possédant une pluralité de parties relief (33) disposée en rang dans une première direction ; et une couche à indice de réfraction variable (32) qui est disposée de manière à remplir l’espace entre les parties relief (33), et dont l’indice de réfraction varie selon la tension appliquée entre la première et la seconde couche d’électrode (40, 50). La première et/ou la seconde couche d’électrode (40, 50) est configurée à partir d’une pluralité de pièces d’électrode. Cette pluralité de pièces d’électrode contient une pluralité de premières pièces d’électrode (51) à laquelle est appliquée une première tension, et une pluralité de secondes pièces d’électrode (52) à laquelle est appliquée une seconde tension. La pluralité de premières pièces d’électrode (51) et la pluralité de secondes pièces d’électrode (52), sont disposées en rang en alternance dans la première direction.
(JA) 光学デバイス(1)は、互いに対向して配置された、透光性を有する第1電極層(40)及び第2電極層(50)と、第1電極層(40)と第2電極層(50)との間に配置され、入射した光を配光する配光層(30)とを備え、配光層(30)は、第1方向に並んで配置された複数の凸部(33)を有する凹凸構造層(31)と、複数の凸部(33)間を充填するように配置され、第1電極層(40)及び第2電極層(50)間に印加される電圧に応じて屈折率が変化する屈折率可変層(32)とを含み、第1電極層(40)及び第2電極層(50)の少なくとも一方は、複数の電極片から構成され、複数の電極片は、第1電位が印加される複数の第1電極片(51)と、第2電位が印加される複数の第2電極片(52)とを含み、複数の第1電極片(51)と複数の第2電極片(52)とは、第1方向に交互に並んで配置されている。
