Volume holographic element, volume holographic element manufacturing method, and display device
First Claim
1. A volume holographic element, comprising:
- a first translucent substrate;
a second translucent substrate that faces the first translucent substrate;
a first holographic material layer that is arranged between the first translucent substrate and the second translucent substrate;
a first translucent anti-reflective layer that is arranged on a first surface of the first translucent substrate, the first surface being a surface opposite to the first holographic material layer; and
a bending section where the first holographic material layer is bent on one side in a thickness direction.

Abstract
In a process of manufacturing the volume holographic element, a holographic material layer is irradiated with reference light from the side of a second substrate in the oblique direction, and the holographic material layer is vertically irradiated with object light from the side of a first substrate in an interference exposure process. Since a first translucent anti-reflective layer is formed on the first surface of the first substrate, it is difficult that situation in which the reference light is reflected in the first surface in the oblique direction occurs. In addition, since a second translucent anti-reflective layer is formed on the second surface of the second substrate, it is difficult that a situation in which the object light is reflected in the second surface occurs.
