Display device

Abstract

The display device includes an image display body whose optical state changes between a transparent state and an opaque screen state, and an image projection unit that projects visible light onto the image display body in the screen state to display an image. The image display body includes a display function layer having liquid-crystal molecules and a photoresponsive alignment change-inducing material, and a reflective layer laminated on the display function layer. The reflective layer has a reflection peak wavelength within 10% of the maximum absorption peak wavelength of the photoresponsive alignment change-inducing material, and the reflectance is 10% or less in the wavelength range of 100 nm or more from the reflection peak wavelength.
