A vehicular display apparatus includes a light source unit that emits laser light; a first optical system that uses a first projection surface, onto which a display image is projected, to make a virtual image discernible; a second optical system that uses a second projection surface, onto which the display image is projected, to make a real image discernible; a controller; and a switching mechanism that switch the two optical systems. The distance between the light source unit and first projection surface is smaller than the distance between the light source unit and second projection surface.
