Abstract:
The purpose of the present invention is to provide a vehicle display device capable of improving the quality of a virtual image while using a multi-view display. A vehicle display device 10 is provided with a multi-view display 30 and an optical system mechanism 70. A flat display panel 32 is disposed at a position which is shorter than a focal length D0 of a lenticular lens 34 and at which light F that has passed through the lenticular lens 34 from the viewer Mn side forms an image on an optical focal plane FH of the optical system mechanism 70 comprising a plane mirror 40, a concave mirror, and a display part. Moreover, disposed on the optical system mechanism 70 side of the lenticular lens 34 is a correction lens 35 both the incident side and the emission side of which have a concave lens shape in the vertical direction, and which causes the light F that has passed through the optical system mechanism 70 and the lenticular lens 34 to form an image on the optical focal plane FH if the light F is emitted from the position of the viewer Mn in the vertical direction of the optical focal plane FH.
