Title:
DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/243223
Kind Code:
A1
Abstract:
This display device comprises an image display body, the optical state of which changes between a transparent state and an opaque screen state, and an image light projecting part for displaying an image by projecting visible light on the image display body in the screen state. The image display body has: a display function layer that contains liquid crystal molecules and a light-responsive orientation change-inducing material; and a reflective layer that is laminated on the display function layer. The reflective layer has a reflection peak wavelength in a range of 10% or less of the maximum absorption peak wavelength of the light-responsive orientation change-inducing material, and the reflectivity in a wavelength range separated from the reflection peak wavelength by 100 nm or more is 10% or less. Therefore, it is possible to provide a display device wherein a reduction of the color reproducibility of an image projected on the image display body can be suppressed.
