Abstract

The invention discloses a liquid crystal lens, a manufacturing method thereof and an optical device. The liquid crystal lens manufacturing method comprises the steps: arranging a first orientation layer on the surface of a first substrate to form a first orientation assembly, and arranging a second orientation layer on the surface of a second substrate to form a second orientation assembly; arranging a plurality of spacers between the first orientation layer and the second orientation layer to form a gap layer; carrying out regional division on the target lens to obtain regional phase diagramsof a plurality of regions, and carrying out normalization processing on the regional phase diagrams to obtain an exposure diagram; orienting the first orientation layer and / or the second orientationlayer according to the exposure image; and performing liquid crystal filling on the gap layer to form a liquid crystal layer. According to the invention, the manufacturing period of the liquid crystallens can be shortened, and the production and processing process is simplified, so that the production efficiency is improved; through the light-operated orientation technology, contact with the orientation layer is not needed, and unnecessary damage to the substrate due to introduction of dust is avoided.

Description

technical field [0001] The invention relates to the field of liquid crystal lenses, in particular to a liquid crystal lens, a manufacturing method thereof, and an optical device. Background technique [0002] In the related art, the method of rubbing alignment is usually used to prepare a liquid crystal lens and align the liquid crystal. However, the rubbing alignment technique will introduce dust impurities during the rubbing process, which will damage the substrate and affect the alignment effect. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a method for manufacturing a liquid crystal lens, which reduces the damage to the substrate by orienting the liquid crystal by using a light-controlled orientation technology, thereby improving the effect of orientation. [0004] The present invention also provides a liquid crystal lens manufactured ...
