Abstract

An optical component including a first layer, a second layer and a bulk sandwiched between the first and second layers, where the bulk is formed by a composition containing a liquid crystal material which is in a blue phase. At least one of the first and second layers has, toward the bulk, an alignment layer. The blue phase of the liquid crystal material exhibits a uniform organization in three directions (Ox, Oy, Oz) in at least 80% of the volume of the bulk, the liquid crystal material being stabilized in the blue phase at least over the temperatures ranging from 10° C. to 35° C.
