Claims (1)
- 고휘도의 백색광을 방사하는 광원(21)과, 상기 광원(21)으로부터 방사된 광을 반사시키는 반사거울(14)과, 상기 반사거울(14)로부터 반사된 광을 소정각도로 집속시키는 필드렌즈(15)와, 상기 필드렌즈(15)에 의해 집속된 광을 소정신호에 따라 화소에 대응하도록 광로를 조절하는 광로조절기(20)와, 상기 광로조절기(20)로부터 광로가 조절된 광을 스크린으로 투사시키는 투사렌즈(16)로 구성된 투사형화상표시장치의 광학계에 있어서, 상기 광원(21)과 반사거울(14)의 사이에는 상기 광원(21)으로부터 방사된 방사광중에서 가시광선을 투과시키고 자외선 및 적외선을 반사시키는 핫미러(22)가 설치되되, 상기 핫미러(22)는 상기 광원(21)으로부터의 백색광중에서 자외선 및 적외선을 광원(21)의 반사면(21a)을 향해 반사시킬 수 있도록 소정각도만큼 경사지게 설치된 것을 특징으로 하는 투사형화상표시장치의 광학계.
