Claim 2:
3. The information display apparatus according to claim 1,
wherein in a case where the information display apparatus is arranged under the reflecting surface to reduce a double image that is generated by a difference between ordinary light reflected by an interface between the reflecting surface and an interior of the conveyance and extraordinary light reflected by an interface between the reflecting surface and an exterior of the conveyance, relative refractive power of a virtual image optical system through which a ray passing through an upper portion than a center of an incident eye passes is set to be smaller than relative refractive power of a virtual image optical system through which a ray passing through a lower portion than a center of the other incident eye passes so that aberration occurs below the main ray of the virtual image optical system.
