Abstract

See full text

Provided is a liquid-crystal lens with low wavefront aberration. A liquid-crystal lens (1) includes a liquid crystal layer (11), a first electrode (21), a second electrode (22), and a high-resistivity layer (41). The first electrode (21) includes: a first electrode portion (21a) including a circular opening (21a1) and a communicating cutout (21a2) formed therein, the communicating cutout (21a2) allowing the circular opening (21a1) to communicate with the outside; and a second electrode portion (21b) including a circular main electrode portion (21b1) disposed within the opening (21a1) and a leading electrode portion (21b2) connected to the main electrode portion (21b1) and disposed within the communicating cutout (21a2). The second electrode (22) faces the first electrode (21) with the liquid crystal layer (11) in between. The high-resistivity layer (41) is disposed between at least the second electrode portion (21b) of the first electrode (21) and the liquid crystal layer (11). The high-resistivity layer (41) has a shape rotationally symmetric about a central axis of the main electrode portion (21b1).
