Abstract

본 발명은 프라이버시 보호 필터 및 그 제조방법에 관한 것으로, 보다 상세하게는 제1 투명 기판과, 상기 제1 투명 기판에 대하여 일정 간격을 두고 서로 마주보도록 배치되는 제2 투명 기판과, 상기 제1 투명 기판 및 제2 투명 기판 사이에 충전된 전해질과, 상기 전해질 및 제2 투명 기판 사이의 제2 투명 도전막을 포함하며, 상기 제1 투명 기판은 상기 제1 투명 기판 위에 형성된 선격자 및 트렌치를 갖는 요철 패턴, 상기 요철 패턴의 선격자 및 트렌치 상에 형성된 제1 투명 도전막, 상기 선격자의 벽면을 따라 제1 투명 도전막 위에 형성되며, 전기의 인가 여부에 따라 가시광선을 투과 또는 흡수하는 전기변색물질을 함유하는 전기 변색층을 포함하는 프라이버시 보호 필터와 그 제조방법을 제공한다. 본 발명의 프라이버시 보호 필터는 빛의 정면 투과율의 저하 없이 측면 투과율만을 효과적으로 차단할 수 있으며, 광시야각 모드 및 협시야각 모드의 전환이 빠르고, 필터의 성능과 구동안정성을 확보할 수 있다.
