Abstract

본 발명은 광로 조절 장치의 광 효율을 높이기에 적합한 투사형 화상 표시 장치의 광로 조절 장치 구조에 관한 것으로, 종래에는 제1도의 경우, 구동시, 거울 기능을 겸하는 바이어스 전극(7)표면이 휘어지게 되므로 광 효율이 저하했으며, 제2도의 경우, 구조가 다수의 층으로 이루어지기 때문에 제조하기가 어렵고 구조가 불안정하였으나, 본 발명에서는 제3도의 경우, 구동시, 신호 전극(24) 좌측 끝 부분에서 변형이 발생하므로써 그 좌측 이상의 부분에 해당하는 바이어스 전극(26)은 곡면없이 경사지므로 광 효율이 높아지며, 제4도의 경우, 구동시, 바이어스 전극(35) 좌측 끝 부분에서 변형이 발생하므로써 그 좌측 이상의 부분에 해당하는 거울(37)은 곡면없이 경사지므로 광 효율이 높아져 즉, 변형 부분을 좁게하고 거울 부분(26)(37)을 넓게하면 광 효율이 더욱 증가하므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to an optical path adjusting device structure of a projection type image display device suitable for increasing the light efficiency of the optical path adjusting device. In the case of FIG. 1, the surface of the bias electrode 7, which also serves as a mirror function, is curved when driven. In the case of FIG. 2, in the case of FIG. 3, the light efficiency is reduced, and the structure is made of a plurality of layers. As a result of this, the bias electrode 26 corresponding to the portion of the left side or more is inclined without a curved surface, so that the light efficiency is increased. In FIG. The mirror 37 corresponding to the surface is inclined without a curved surface, so that the light efficiency is increased, that is, narrowing the deformed portion and widening the mirror portions 26, 37 results in the light efficiency. It will further increase to improve the above drawbacks.
