Optical component comprising blue phase liquid crystal and method for making such an optical component

摘要

The present invention relates to an optical component (1) including a first layer (10), a second layer (20), and a bulk (50) sandwiched between the first and second layers. Wherein the bulk is formed by a composition comprising a liquid crystal material (55) in the blue phase (56); and- at least one of the first and second layers faces the bulk and the alignment layer (15, 25). And the blue phase of the liquid crystal material exhibits a uniform texture in at least 80% of the bulk volume in three directions (Ox, Oy, Oz), wherein the liquid crystal material is at least 10 ° C to 35 ° C. The optical component (1) is stabilized in the blue phase over a temperature in the range of
