Abstract

본 발명은, 예를 들면, 콜레스테릭 상의 키랄 액정 측쇄 중합체의 층에 직각 방향으로 전기장을 적용시켜 광학 피터 또는 지연 장치에 사용되는 키랄 액정 측쇄 중합체(3)막의 층에 불가피하게 나타나는 바람직하지 않은 간섭성 사선을 제거하는 방법에 관한 것이다.

Description

키랄 액정을 반대방향 사선(disclination)이 발생되지 않도록 하면서 배향시키는 방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 두 판 사이의 키랄 액정 측쇄 중합체 층의 단면도이다.

Claims (5)

  1. 콜레스테릭 상에서 네가티브 유전 이방성을 갖는 키랄액정 측쇄 중합체(3)층에 직각 방향으로 전기장을 건 다음, 중합체를 이의 유리전이온도 이하로 냉각시킴으로써 전기장에 의해 유도된 배향을 고정시킴을 포함하여,키랄 액정 측쇄 중합체에 반대방향 사선이 발생되지 않도록 하면서 평면 배향을 부여하는 방법.
  2. 반대방향 사선이 발생되지 않도록 배향된 액정 측쇄 중합체 층을 갖는 광학 부품.
  3. 제2항에 있어서, 층이 평면 벽 배향 층을 제공하는 2개의 기판 사이에 배열된 광학 부품.
  4. 제2항에 있어서, 층이 평면 벽 배향 층을 제공하는 1개의 기판 위에 배열된 광학 부품.
  5. 제3항 또는 제4항에 있어서. 배항시킨 전기장에 적용할 경우 기판(들)위에 임의로 분할된 전극을 갖는 광학부품.
