Title (EN) POLARISING LIQUID CRYSTAL DEVICE
(FR) DISPOSITIF À CRISTAUX LIQUIDES À POLARISATION
Abstract:
(EN) A method of forming a polarising liquid crystal device, including the step of: embossing at least one relief structure in a radiation curable liquid crystal material, whereby the embossing step also aligns the liquid crystal material with a predetermined polarisation pattern. The method also includes curing the embossed liquid crystal material, the curing and embossing steps being carried out substantially simultaneously. Also described is a polarising liquid crystal device including at least one relief structure in an embossed area or areas of a radiation curable liquid crystal device. The relief structure may include a diffractive structure. The liquid crystal material may be aligned with a predetermined polarisation pattern in the embossed area or areas, the predetermined polarisation pattern including two or more areas having different polarisations.
(FR) L'invention porte sur un procédé de formation d'un dispositif à cristaux liquides de polarisation, lequel procédé comprend l'étape consistant à : gaufrer au moins une structure en relief dans un matériau de cristal liquide durcissable aux rayonnements, ce par quoi l'étape de gaufrage aligne également le matériau de cristal liquide avec un motif de polarisation prédéterminé. Le procédé comprend également le durcissement du matériau de cristal liquide gaufré, les étapes de durcissement et de gaufrage étant effectuées sensiblement simultanément. L'invention porte également sur un dispositif à cristaux liquides de polarisation, lequel dispositif comprend au moins une structure en relief dans une zone ou dans plusieurs zones gaufrées d'un dispositif à cristaux liquides durcissable aux rayonnements. La structure en relief peut comprendre une structure à diffraction. Le matériau de cristal liquide peut être aligné avec un motif de polarisation prédéterminé dans la zone ou dans les zones gaufrées, le motif de polarisation prédéterminé comprenant deux ou plusieurs zones ayant des polarisations différentes.
