Abstract
UN DISPOSITIVO DE CRISTAL LIQUIDO SE FORMA MEDIANTE LA APLICACION DE UNA PELICULA DE ALINEAMIENTO QUE COMPRENDE UNA POLIIMIDA CONTENIENDO FLUOR, QUE TIENE UN SUBSTITUYENTE DE UN ATOMO DE FLUOR, O FLUOR CONTENIENDO GRUPO EN SU MITAD ORIGINADA DE ANHIDRIDO DE ACIDO CARBOXILICO, SOBRE, AL MENOS, UNO DE UN PAR DE SUBSTRATOS INTERCALANDO UN CRISTAL LIQUIDO ESMECTICO QUIRAL. PREFERENTEMENTE, LOS SUBSTRATOS RESPECTIVOS SE PROPORCIONAN CON TALES PELICULAS DE ALINEAMIENTO DE POLIIMIDA CONTENIENDO FLUOR, QUE HAN SIDO FROTADAS EN DIRECCIONES QUE SON SUSTANCIALMENTE PARALELAS UNAS A OTRAS, E IDENTICAS UNAS A OTRAS, O QUE SE ENTRECRUZAN UNAS A OTRAS, EN UN ANGULO PEQUEÑO DE INTERSECCION A LA IZQUIERDA. EL DISPOSITIVO DE CRISTAL LIQUIDO ASI FORMADO MUESTRA UNA PANTALLA DE GRAN CONTRASTE, PARTICULARMENTE MEDIANTE TRANSMISION SIMULTANEA, LIBRE DE IMAGEN CONSECUTIVA, DEBIDO A LA RAPIDA CORRESPONDENCIA.
