A backlight unit includes a light source; a condensing unit that condenses light emitted from the light source; and a diverging unit that diverges the light entering from the condensing unit and that emits the light toward an image display unit of a light transmission type in a head-up display device. For example, the diverging unit is a lens in which both surfaces of an incident surface into which the light from the condensing unit enters as well as an emission surface from which the light is emitted toward the image display unit, are concave surfaces.

Backlight unit and head-up display device

A head-up display device includes a housing, a reflecting member, a projection light emitting unit, and a vibration transmitting member. The housing is fixed to a vehicle. The reflecting member is rotatably supported by the housing and is held at a rotation position. The projection light emitting unit projects projection light corresponding to information onto a window of the vehicle through the reflecting member. The vibration transmitting member is provided between the housing and the reflecting member and has elasticity. The vibration transmitting member is fixed to the housing and makes contact with the reflecting member in an elastically compressed state in an entire rotatable range of the reflecting member.
