Abstract

본 발명은 화질의 질을 높게 하기에 적합한 투사형 화상 표시 장치의 광로 조절 제조 방법에 관한 것으로, 종래에는 구조적으로 복잡하게 이루어져 있기 때문에 수명이 짧으며, 제조 공정이 불안정하여 전체 픽셀의 균일도가 떨어졌으나, 본 발명에서는 각 지지부(21)가 각 픽셀을 양 끝단에서 고정하도록 하므로써 구조적으로 안정하며, 픽셀을 균일하게 형성하므로 화질이 개선되어 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to a light path control manufacturing method of a projection type image display device suitable for increasing the quality of the image quality, and has a short lifespan because the structure is complicated in the prior art, the manufacturing process is unstable, the uniformity of the entire pixel is reduced. In the present invention, each support 21 is structurally stable by fixing each pixel at both ends, and since the pixels are uniformly formed, the image quality is improved, thereby improving the above-mentioned defects.
