Abstract

본 발명은 광로 조절 장치 구조가 안정하게 되도록 하기에 적합한 투사형 화상 표시 장치의 광로 조절 장치 구조에 관한 것으로,종래에는 구조적으로 복잡하기 때문에 제조하기가 어렵고 장시간 구동시,고장 발생이 쉬웠으나,본 발명에서는 광로 조절 장치의 구조를 간단하게 형성하므로써 제조 공정이 간단해지고 장시간 구동시에도 신뢰성이 지속되므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to an optical path adjusting device structure of a projection type image display device which is suitable for making the optical path adjusting device structure stable. In the related art, it is difficult to manufacture because it is structurally complicated, and it is easy to cause breakdown when driving for a long time. By simply forming the structure of the optical path control device, the manufacturing process is simplified and the reliability is maintained even during long time driving, thereby improving the above-mentioned shortcomings.
