OPTICAL COMPONENT COMPRISING LIQUID CRYSTALS IN A BLUE PHASE AND PROCESS FOR MAKING SUCH OPTICAL COMPONENT

The invention relates to an optical component (1) comprising a first layer (10), a second layer (20) and a bulk (50) sandwiched between said first and second layers, wherein - the bulk is formed by acomposition comprising a liquid crystal material (55) which is in a blue phase (56), - at least one of the first and second layers has, toward the bulk, an alignment layer (15, 25), and - 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, said liquid crystal material being stabilized in said bluephase at least over the temperatures ranging from 10DEG C to 35 DEG C. 本发明涉及光学组件(1)，其包含第一层(10)、第二层(20)和夹在所述第一和第二层之间的主体(50)，其中-所述主体由包含蓝相(56)液晶材料(55)的组合物形成，-第一和第二层的至少一个具有朝向所述主体的配向层(15、25)，和-液晶材料的蓝相在主体体积的至少80％中表现出在三个方向(Ox、Oy、Oz)上的一致组织，所述液晶材料至少在10℃至35℃的温度范围内稳定在所述蓝相中。
