Title:
OPTICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/034293
Kind Code:
A1
Abstract:
This optical device includes: a light source; and an optical element that includes a plurality of liquid crystal cells which are layered and that controls distribution of light emitted from the light source. The plurality of liquid crystal cells each include: a first substrate (110-1) in which first electrodes (120-1) and second electrodes (120-2) are arranged alternatingly; a second substrate in which third electrodes and fourth electrodes are arranged alternatingly; and a liquid crystal layer between the first substrate and the second substrate. The first electrodes and the second electrodes each include: a first linear section (LP11) that extends at an angle α° with respect to a first direction; and a second linear section (LP 12) that extends at an angle β° with respect to the first direction. The third electrodes and the fourth electrodes each include: a third linear section that extends at an angle (90+α)° with respect to the first direction; and a fourth linear section that extends at an angle (90+β)° with respect to the first direction.
