Title (EN) REFLECTIVE LIQUID CRYSTAL CELL
(FR) CELLULE À CRISTAUX LIQUIDES RÉFLÉCHISSANT
(JA) 反射型液晶セル
Abstract:
(EN) This reflective liquid crystal cell is characterized by comprising: a first polarizing plate (2) which transmits one of polarization components that are perpendicular to each other, while reflecting the other; a liquid crystal unit (3) which is arranged on the front surface (2a) side of the first polarizing plate (2); a second polarizing plate (4) which is arranged on the front surface (3a) side of the liquid crystal unit (3), and which transmits a specific polarization component of incident light incident thereon to the liquid crystal unit (3), while transmitting the incident light from the liquid crystal unit (3); a transparent heave absorption layer (5) which is formed from a resin and is arranged on the front surface (4a) of the second polarizing plate (4); and a cover glass (6) which is arranged on the front surface (5a) of the heave absorption layer (5). This reflective liquid crystal cell is also characterized in that the heave absorption layer (5) bonds the second polarizing plate (4) and the cover glass (6) to each other and absorbs heaves of the front surface (4a) of the second polarizing plate (4).
(FR) Cette cellule à cristaux liquides réfléchissant est caractérisée en ce qu'elle comprend : une première plaque de polarisation (2) qui transmet l'une des composantes de polarisation qui sont perpendiculaires l'une à l'autre, tout en réfléchissant l'autre; une unité à cristaux liquides (3) qui est disposée sur le côté de la surface avant (2a) de la première plaque de polarisation (2); une seconde plaque de polarisation (4) qui est disposée sur le côté de la surface avant (3a) de l'unité de cristaux liquides (3), et qui transmet une composante de polarisation spécifique de la lumière incidente incidente sur celle-ci à l'unité à cristaux liquides (3), tout en transmettant la lumière incidente provenant de l'unité à cristaux liquides (3); une couche d'absorption de pilonnement transparente (5) qui est formée à partir d'une résine et qui est disposée sur la surface avant (4a) de la seconde plaque de polarisation (4); et un verre de recouvrement (6) qui est disposé sur la surface avant (5a) de la couche d'absorption de pilonnement (5). Cette cellule à cristaux liquides réfléchissant est également caractérisée en ce que la couche d'absorption de pilonnement (5) lie la seconde plaque de polarisation (4) et le verre de couverture (6) l'une à l'autre et absorbe les minéraux lourds de la surface avant (4a) de la seconde plaque de polarisation (4).
(JA) 直交する偏光成分のいずれか一方を透過させるとともに他方を反射させる第一偏光板(2)と、第一偏光板(2)の前面(2a)側に配置された液晶部(3)と、液晶部(3)の前面(3a)側に配置され、入射した入射光の所定の偏光成分を液晶部(3)に透過させるとともに、液晶部(3)からの入射光を透過させる第二偏光板(4)と、第二偏光板(4)の前面(4a)に配置され、樹脂製の透明なうねり吸収層(5)と、うねり吸収層(5)の前面(5a)に配置されたカバーガラス(6)と、を有し、うねり吸収層(5)は、第二偏光板(4)とカバーガラス(6)とを接着するとともに、第二偏光板(4)の前面(4a)のうねりを吸収することを特徴とする。
