Document Type and Number:
WIPO Patent Application WO/2015/016685
Kind Code:
A1
Abstract:
The present application relates to an oriented film for a liquid-crystal lens, to a mould for forming same and to production methods for the oriented film and for the mould, and can provide an oriented film whereby it is possible to effectively produce a liquid-crystal lens in which the liquid crystal is well oriented on the inside thereof, and a mould for forming the oriented film. More particularly, the present application makes it possible to form a liquid crystal lens; with effective orientation of the liquid crystal which fills a space having a non-planar surface such as a curved surface in order to achieve the lens shape.
