Abstract: To provide a cover member excellent in edge safety, and a display device in which said cover member is used. A cover member which covers a display panel of a display device and which has a front surface that does not face the display panel and a rear surface that faces the display panel, said cover member being a laminate in which a first glass plate constituting said front surface and a second glass plate constituting said rear surface are bonded via an intermediate film interposed therebetween, wherein the first glass plate has a first inside chamfer which is a chamfer on the intermediate film side, and the first inside chamfer and the second glass plate or the intermediate film are bonded by a resin.

Abstract: A cover glass for covering a display panel of a display device, includes a front surface not to be faced to the display panel, a back surface to be faced the display panel, a front-side chamfered part which is a chamfered part on the side of the front surface, and a back-side chamfered part which is a chamfered part on the side of the back surface. The front-side chamfered part has a surface roughness Ra of more than 100 nm. The back-side chamfered part has a surface roughness Ra of 100 nm or less.

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).
