VEHICLE DISPLAY DEVICE

An in-vehicle display device includes n layers from a cover glass to a housing bottom member, including a display panel midway thereof. The housing bottom member is fixed to an interior portion of a vehicle at at least two fixing points. When a virtual plane R is defined based on the two fixing points, a distance Zis defined based on a main surface of the cover glass and the virtual plane R, and a distance Z is defined based on a main surface of the display panel and the virtual plane R, a ratio Z/Zis 0.6 or less. When a virtual line L is defined based on the main surface of the display panel and the virtual plane R, the n layers satisfy Expression (1).
