Abstract
An information display device is attachable to a structure, and includes a display panel and a surface member. The display panel has a display surface and is configured to display information on the display surface. The surface member is disposed on a display surface side of the display panel and is configured such that only the information displayed on the display surface of the display panel is visible through the surface member when the display panel is turned on. The surface member includes a first layer disposed on a front side, and a second layer disposed on the display panel side with respect to the first layer. The second layer is configured to compensate for a difference of transmittance depending on a position on the first layer.
