Abstract
An information display apparatus emits an image forming light beam to a transmissive reflection member and makes a virtual image visible through the reflection member. The information display apparatus is configured to display the virtual image so that a difference between a convergence angle when viewing the virtual image through the reflection member and a convergence angle when viewing a real object through the reflection member is less than or equal to 1 degree.
