Abstract

Mejoras introducidas en el objeto de la patente principal nº 454.817 registrada el 5 de Enero de 1977 por ¿Una célula de representación visual mejorada ¿ caracterizada porque se provee una célula de representación visual de un cristal líquido esmético con electrodos internos, teniendo una capa de un material esmético entre dos placas que tienen unos electrodos que se solapan al menos en parte, estando cada uno de dichos electrodos cubierto de una capa coherente eléctricamente aislante cuya superficie ha sido tratada para darle una textura rugosa.
