Abstract

상하 기판들(2, 3)상에 각기 띠형전극들(4, 5)를 형성한 후 상기 기판들(2, 3)간에 상호평행 관계로 직사각단면을 갖는 복수의 밀봉된 선형틈들 R이 형성되도록 복수의 구획부재들(8)이 띠형상으로 형성되며, 상부측 러빙방향 A1은 하부측 러빙방향 A2과 소정 교차각도로 교차하며, 구획부재(8)의 연장방향 K는 상기 교차각도내이며, 반강유전성액정은 상기 선형틈내에 주입된 후 선형틈들 R의 일단으로부터 타단으로 액정판넬을 냉각시키며, 반강유전성액정용 액정판넬구조는 우수한 충격방지성 및 내충격성을 제공하며, 상하 기판간에서 불규칙해지는 액정분자층의 충법선방향이 교차러빙방법의 사용에 의해 방지되며 그에 의해 액정내의 결함발생을 피할 수 있고 또한 지그자그결함의 발생은 반강유전성액정의 주입을 제어하고 또한 냉각을 제어함으로써 방지된다.
