Abstract
An image display device includes at least one transmissive display panel arranged at different depth positions in a direction normal to a display surface of the image display device. Each of the transmissive display panels includes a light-emitting layer that is sandwiched between a front side transmissive film and a rear side transmissive film. The rear side transmissive film has an interface with a maximum refractive index difference that causes an efficiency of light emitted from the light-emitting layer to become smaller than a front side light emission efficiency in the characteristics of light-emission efficiency, which changes with respect to a film thickness of the transmissive film due to optical interference.
