Abstract
(Object) To provide an information display device, with a simple configuration, that is capable of reducing stress in perceiving information. (Means of Achieving the Object) The disclosed information display device irradiates a transparent-reflective member with light for forming an image, in order to display a virtual image of the image on the transparent-reflective member. The information display device includes: a plurality of light sources having different peak emission wavelengths, respectively, which are provided for generating the light for forming the image; a vision-related information input unit configured to receive an input of information relating to vision of a viewer viewing the virtual image; and a luminance adjusting unit configured to adjust luminance of each of the plurality of light sources, independently, based on the information input into the vision-related information input unit.
