Reflecting mirror and projection type image display apparatus using the same |
摘要 |
The present invention is directed to the provision of a reflecting mirror that suppresses decreases in the resolution performance and contrast performance by decreasing the mean surface roughness. In a projection type image display apparatus including a projector lens that expansion projects the image light from an image generating source and a reflecting mirror that guides the image light from the projector lens to the back face of the screen, according to the present invention, a silver reflecting surface ( 2 ) is formed on the substrate ( 1 ) of the reflecting mirror, a protective layer ( 3 ) of a transparent resin is formed thereon, and the mean surface roughness of the silver reflecting layer is made to be 1.8 nm or less.
