Abstract

Disclosed is a liquid crystal optical element having a multilayer structure, said liquid crystal optical element being easily processed, ensuring a liquid crystal filling quantity and sufficient optical distance (L), and having an improved response speed and light transmittance. Also disclosed is a method for manufacturing such liquid crystal optical element. The liquid crystal optical element (100) having the multilayer structure is provided with: a first unit element (10) wherein a liquid crystal (40) is filled between a substrate (10a) having a segment electrode formed thereon, and a substrate (10b) having no electrode formed thereon; a second unit element (20) wherein the liquid crystal (40) is filled between a substrate (20a) having no electrode formed thereon, and a substrate (20b) having a common electrode formed thereon; and third unit elements (30) wherein the liquid crystal (40) is filled between substrates (30a, 30b) having no electrode formed thereon. Four third unit elements (30) are disposed and laminated between the first unit element (10) and the second unit element (20). Furthermore, the liquid crystal alignment direction in the first unit element (10) and that in the upper two third unit elements (30), and the liquid crystal alignment direction in the second unit cell (20) and that in the lower two third unit elements (30) orthogonally intersect each other.

Description

technical field [0001] The invention relates to a multi-layer structure liquid crystal optical element with a plurality of liquid crystal layers between a substrate formed with a segment electrode and a substrate formed with a common electrode and a manufacturing method thereof. Background technique [0002] Conventionally, various liquid crystal optical elements are known in which liquid crystal is sandwiched between substrates on which electrodes are formed. For example, as information recording media, there are various optical disc devices such as CD and DVD. However, in these optical disc devices, aberrations (distortion of the light-converging point) occur due to factors such as thickness deviation and curvature caused by rotation, so it is necessary to This aberration is corrected to ensure recording and reproduction accuracy. Therefore, by using a liquid crystal aberration correction element sandwiching a liquid crystal on a concentric ring-shaped substrate on which ...
