Abstract: The present invention relates to a vehicle-mounted display device disposed in an interior member of a vehicle. The vehicle-mounted display device of the invention includes: a display panel; a cover glass covering the display panel; a housing accommodating the display panel; and a holding portion holding a position of the housing, in which the cover glass is a tempered glass having a thickness being 0.5 to 2.5 mm, a thickness of a compressive stress layer being 10 μm or more, and a surface compressive stress of the compressive stress layer being 650 MPa or higher, and when the thickness (unit: mm) of the cover glass is represented by x and an energy absorption rate (unit: %) of the holding portion is represented by y, Expression (1) is satisfied, and impact resistance of the cover glass is excellent: y≥−37.1×ln(x)+53.7  (1).
