Abstract:
A display device, comprising:a light source; a light guide having a light-receiving surface for receiving light from the light source and a light-exiting surface for emitting the light, which has entered the light guide through the light-receiving surface; a reflection type display element provided on one side of the light guide that is closer to the light-exiting surface; and a refractive-index-adjusted layer provided between the light guide and the reflection type display element and having a different refractive index from that of the light guide, wherein: the light guide and the reflection type display element are attached to each other via the refractive-index-adjusted layer; and at least one of an interface between the light guide and the refractive-index-adjusted layer and an interface between the refractive-index-adjusted layer and the reflection type display element is subjected to an anti-interface-reflection treatment for suppressing a reflection of light at the interface.
