Abstract

편광판, 위상차편광판 또는 위상차판의 한쪽 표면에 접착층을 형성시키고, 이 접착층의 표면에 투명한 이축배향 방향족 폴리에스테르 필림을 베이스 필름으로 한 이형필림을 형성시킨 적층체에 있어서, 상기 적층체가 마이크로파 투과형 분자배향기로 측정한 상기 이형필림에 있어서 이축배향 방향족 폴리에스테르 필림의 배향주축의 방향(1)과 편광판, 위상차편 광판 또는 위상차판의 배향축의 방향(2)이 실질적으로 동일하거나 또는 실질적으로 90도의 각도를 이루도록 되어 있음을 특징으로 하는 편광 특성을 개선시킨 적층체. 본 발명의 적층체는 대형의 TFT방식 또는 STN방식의 편광판, 위상차편광판 또는 위상차판을 시각적으로 검사할 때 이물질 또는 결합을 용이하게 발견하도록 해준다.
