Abstract

An object of the present invention is to provide a vehicle that includes a display panel, a light source that irradiates light to the display panel, a first optical system that forms, onto a screen plate, a first optical image of a video on the display panel, and a second optical system that converts the first optical image into a second optical image that is a virtual image. The first and second optical systems are configured such that the first optical system's optical axis, at an incident surface side of the screen plate, is parallel to the second optical system's optical axis at an emission surface side of the screen plate. The first optical image formed on the screen plate is obtained by enlarging the video, and the virtual image is obtained by enlarging the first optical image formed on the screen plate by the second optical system.
