Abstract

디스플레이용으로 사용되는 피디엘씨 패널의 피디엘씨 층의 균일한 중합 방법이 개시되어 있다.
중합 반응의 제어가 용이한 자외선에 의한 광중합을 중합에 사용하는 경우에, 피디엘씨 패널에 설치되어 있는 차광층 등에 의해 자외선의 투과가 차단되는 부분에서 중합이 제대로 이루어지지 않으며, 이에 따라 피디엘씨층의 광학적 및/또는 기계적 성질이 열화되는 문제가 있다.
이와 같은 문제를 해결하기 위하여 자외선 흡수제를 중합시에 혼합하여 사용하고, 액정 패널의 양쪽에서 조사각을 변화시키면서 자외선을 조사하여 균일한 중합이 이루어지도록 하였다.
이와 같이 자외선 흡수제를 혼합하여 사용하는 중합 방법은 피디엘씨 패널과 같이 자외선이 차단되는 부분이 작은 크기로 전반적으로 균일하게 분포되어 있는 다른 경우의 중합에도 사용될 수 있으며, 이러한 방식으로 제작된 피디엘씨 패널은 각종의 디스플레이 장치에 사용될 수 있다.
