1. A display device for a vehicle, comprising:
a liquid crystal display device that includes a display surface for displaying an image; and
an optical system that includes a reflecting surface and that forms an optical path of display light from the display surface toward an eye point of a vehicle, wherein
the optical system includes a first reflecting surface placed closest to the display surface in the optical path of the display light, and a magnifying reflecting surface that magnifies and reflects the display light,
when viewed from an image horizontal direction, the display surface is inclined toward an optical axis of the display light extending from the display surface toward the first reflecting surface, and
the optical system is configured so that a width of the optical path of the display light in an image vertical direction is reduced, gradually from the display surface toward the first reflecting surface.
