Abstract

DISPOSITIVO DE CRISTAL LIQUIDO QUE INCLUYE: (A) DOS SUBSTRATOS; (B) UN ELECTRODO ALARGADO (12A) SITUADO EN EL PRIMER SUBSTRATO Y OTRO (12B) EN EL SEGUNDO SUNBSTRATO DE MANERA QUE INTERSECCIONA CON EL PRIMERO (12A) Y FORMA UN PIXEL (P2) EN DICHA INTERSECCION DE AMBOS ELECTRODOS; (C) UN BORDE LINEAL (13A) DISPUESTO A LO LARGO DE LA EXTENSION DE AL MENOS UNO DE LOS DOS ELECTRODOS; Y (D) UN CRISTAL LIQUIDO QUIRAL Y ESMECTICO SITUADO ENTRE AMBOS SUBSTRATOS EN UN ESPESOR PEQUEÑO SUFICIENTE PARA EVITAR LA FORMACION DE LAS ESTRUCTURAS HELICOIDALES INHERENTES AL CRISTAL LIQUIDO QUIRAL Y ESMECTICO EN SU ESTADO LIBRE. EL CRISTAL LIQUIDO FORMA UN CAMPO CON UN ESTADO DE ALINEACION DEL MISMO CON UNA INCLINACION QUE FORMA UN PAR DE DEFECTOS, UNO CON FORMA DE HORQUILLA (14) Y UN DEFECTO DE CENTELLEO, DISPUESTOS DE TAL FORMA QUE EL DEFECTO DE HORQUILLA ESTA MAS PROXIMO AL BORDE LINEAL (13A) QUE EL CENTELLEANTE (15).
