A method of aligning a liquid-crystalline compound in a direction different from the direction of stretching or rubbing. The method is characterized by subjecting a hydroxylated polymeric film to (a) stretching and esterification or (b) esterification and then rubbing and subsequently forming a layer of a liquid-crystalline compound on the film to thereby align the liquid- crystalline compound in a direction different from the stretching direction in the case of (a) or in a direction approximately perpendicular to the rubbed film surface in the case of (b).
L'invention concerne un procédé permettant d'aligner un composé cristallin liquide dans un sens différent du sens d'étirage et de polissage. Ce procédé est caractérisé en ce qu'un film hydroxylé est soumis a) à un étirage et à une estérification ou b) à une estérification, puis à un polissage, formant ainsi une couche de composé cristallin liquide sur ledit film de façon à aligner ledit composé cristallin liquide dans un sens différent du sens d'étirage dans le cas de a) ou dans un sens approximativement perpendiculaire à la surface du film poli dans le cas de b).
