Description
Claims (2)
- 광빔을 출사하는 광원(42)과, 상기 광원(42)으로부터 출사되는 광빔을 통과시켜 평행광으로 변환하는 콜리메이팅렌즈(34)와, 상기 평행광이 입사되는 액정표시소자(35)를 구비하여 된 프로젝터용 화상투사 장치에 있어서, 상기 콜리메이팅렌즈(34)와 상기 액정표시소자(35) 사이에는 구동수단(40)에 의해 초기위치로부터 광빔의 입사방향에 대해 소정각도회동되도록 설치되어 입사 광빔의 전체 파장 대역을 이동시키는 색보정필터(36)를 구비하는 것을 특징으로 하는 프로젝터용 화상투사 장치.
- 제1항에 있어서, 상기 색보정필터(36)는, 다층박막 코팅한 이색미러(Diachronic Mirror)인 것을 특징으로 하는 프로젝터용 화상투사 장치.
