Diffractive optical member and virtual image display device |
| abstract |
A diffractive optical member includes: a hologram element, a substrate that supports the hologram element, a dielectric film that is provided between the hologram element and the substrate, a buffer layer that is formed around the hologram element so as to buffer a stress applied to the hologram element from outside of the hologram element, and an adhesive layer that makes the buffer layer and the dielectric film adhere to each other. |
