Abstract

플랫-패널 화상 표시장치(1)는 표시될 화상에 따라 패널안에 결속되는 편광된 광의 편광 상태를 조절하기 위한 화상 표시 패널(3)을 포함한다. 상기 광은 화상 표시 패널(3)와 일체된 또는 일체되지 않은 반사 편광자(31)에 의해 편광된다. 상기 화상 표시 패널(3)의적어도 일부는 특히 조절하기에 적합하지 않은 편광 상태를 갖는 빔소자에 대한 광학 도파관으로 기능한다. 분석기(27)는 화상 표시 패널(3)의 제1면(25)에 위치한다. 반사 편광자(31) 형상의 편광 수단은 화상 표시 패널(3)의 제2면(29)에 위치하며, 이 면은 제1면(25)에 대향 위치한다. 광지시 시스템(33)은 화상 표시 패널(3)로부터 이격된 편광자(35)의 표면에 위치하며, 상기 시스템은 여전히 예정 편광 상태를 갖는 광으로 전환될 수 있도록 상 형성에 기여하지 않고 상기 면(35)에서 화상 표시 패널(3)을 이탈하는 광을 다시 화상 표시 패널(3)로 전송시키기 위해 사용된다.
