MULTIPLE ALIGNMENT METHOD IN LIQUID CRYSTALLINE MEDIUM

摘要

The present invention is relative to a method to realize a liquid crystal tri-dimensional aligned structure (100), including: Providing a first substrate (2) having a first surface (2a); Forming a liquid crystal layer (6) in contact to said first surface (2a), said liquid crystal layer including a polymerizable liquid crystal compound; Realizing a first aligning formation (10, 10a, 10b, 20a, 30a, 40a, 50a, 60a) within said liquid crystal layer (6) by irradiating a first portion of said liquid crystal layer with electromagnetic or electron beam radiation according to a given first pattern, so that said first portion of liquid crystal compound becomes polymerized and said first aligning formation (10, 10a, 10b, 20a, 30a, 40a, 50a, 60a) is made of said polymerized liquid crystal compound according to said given first pattern, said first aligning structure defining a first aligning axis (F1, F2); Locally orienting optical axes of molecules of said liquid crystal layer (6) along said first aligning axis (F1, F2).
