Abstract

La invencion está dirigida a una pantalla cristalina líquida que comprende una celda de pantalla que contiene material cristalino líquido y una capa de retardo, dicha capa de retardo comprendiendo una capa de material de peso molecular alto, de preferencia ligeramente entrelazada y un substrato, en donde el material de peso molecular alto tiene una fase neumática por arriba de su Tv y una viscosidad dinámica a la temperatura de trabajo de por lo menso 100 Pa.s y la diferencia de la Ta del material de peso molecular ato y la Ta del material de peso molecular bajo de la celda de pantalla (T8celda) esta en la escala de -301C a +30 degree C, preferiblemente en la escala de -20 degree C a +20 degree C y muy preferiblemente en la escala de -10 degree C a + degree 0 degree C; y la Tv del material cristalino líquido de peso molecular alto es menor de 50 degree C; se encontro que si se usa material de peso molecular alto con una Tc comparable con la del material cristalino líquido preferiblemente de peso molecular bajo la celda activa, la dependencia de la temperatura del valor de retardo de la capa de retardo es comparable con la de la celda activa; de esta manera, el valor de retardo de la capa de retardo es comparable con el de la celda activa dentro de la escala de temperatura en la cual se usan pantallas; también se encontro que entrelazando el material cristalino líquido de peso molecular alto, las capas de retardo de conformidad con la invencion se vuelven menos susceptibles a la formacion de agujeros pequeños y variacion indeseable de la torsion, y tienen estabilidad mecánica mejorada.
