DISPLAY DEVICE FOR VEHICLE

A display device (1) for a vehicle includes a liquid crystal display device (2) including a display surface (41) for displaying an image; and an optical system (3) including a reflecting surface, and forming an optical path (20) of display light (30) from the display surface toward an eye point (EP) of a vehicle. The optical system includes a first reflecting surface (31a) placed closest to the display surface in the optical path of the display light, and a magnifying reflecting surface (32a, 33a) that magnifies and reflects the display light. When viewed from an image horizontal direction, the display surface is inclined toward an optical axis (30x) of the display light extending from the display surface toward the first reflecting surface. The optical system is configured so that a width (Wd) of the optical path of the display light in an image vertical direction (V) is reduced, gradually from the display surface toward the first reflecting surface.
