Description
Claims (1)
- 고휘도의 백색광을 방사하는 광원(11)과, 상기 광원(11)으로부터의 입사광이 소스렌즈(12) 및 소스스톱(13)을 지나 반사거울(14)에 의해 반사되고, 광로조절기(30)의 미러어레이(30c)에 의해 반사되어 투사스톱(40)의 투과공(40a)을 통과하고, 투사렌즈(16)를 통해 스크린으로 투사되도록 된 투사형화상표시장치의 광학계에 있어서, 상기 광로조절기(30)의 미러어레이(30c)는 대각선방향으로 틸팅되어 입사광을 모듈레이션하도록 되어있고, 상기 투사스톱(40)의 투과공(40a)은 중앙부에 마름모꼴로 형성된 것을 특징으로 하는 투사형화상표시장치의 광학계.
