Abstract
(EN)
The objective of this liquid crystal lens (1) is to reduce wave aberration, and is provided with a liquid-crystal layer (11), a first electrode (21), a second electrode (22), and a high-resistance layer (41). The first electrode (21) has: a first electrode part (21a) in which are provided a circular opening (21a1), and a communication port (21a2) for providing communication between the opening (21a1) and the exterior; and a second electrode part (21b) including a circular main electrode part (21b1) disposed inside the opening (21a1), and a draw-out electrode part (21b2) connected to the main electrode part (21b1) and disposed in the communication port (21a2). The second electrode (22) faces the first electrode (21) via the liquid-crystal layer (11). The high-resistance layer (41) is disposed between the liquid-crystal layer (11) and at least the second electrode part (21b) of the first electrode (21). The high-resistance layer (41) has a shape that conforms to rotation with respect to the center axis of the main electrode part (21b1).

L'invention concerne une lentille à cristaux liquides (1) qui permet de réduire les aberrations d'onde, et qui comprend une couche de cristaux liquides (11), une première électrode (21), une seconde électrode (22), et une couche à haute résistance (41). La première électrode (21) comprend : une première partie d'électrode (21a) dans laquelle sont formés une ouverture circulaire (21a1) et un port de communication (21a2) assurant la communication entre l'ouverture (21a1) et l'extérieur ; et une seconde partie d'électrode (21b) comprenant une partie d'électrode principale circulaire (21b1) disposée dans l'ouverture (21a1) et une partie d'électrode de sortie (21b2) connectée à la partie d'électrode principale (21b1) et disposée dans le port de communication (21a2). La seconde électrode (22) fait face à la première électrode (21) vi la couche de cristaux liquides (11). La couche de haute résistance (41) est disposée entre la couche de cristaux liquides (11) et au moins la seconde partie d'électrode (21b) de la première électrode (21). La couche de haute résistance (41) possède une forme qui s'adapte à la rotation par rapport à l'axe central de la partie d'électrode principale (21b1).
