Abstract: The present invention relates to a glass plate including a first main surface subjected to antiglare treatment, and a second main surface opposed to the first main surface, in which a clarity index value T, a reflection image diffusiveness index value R and an anti-sparkle index value S satisfy respective relations of: clarity index value T≥0.8; reflection image diffusiveness index value R≥0.01; and anti-sparkle index value S≥0.85; and a transmission haze measured by a method according to JIS K 7136 (2000) being 15% or less. The glass plate of the present invention is excellent in clarity, reflection image diffusiveness and anti-sparkle, and also excellent in reproducibility of color.

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 a compressive 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).

Abstract: There is provided an optical device including a display device, and a transparent substrate that is disposed on a side of a display surface of the display device. When the transparent substrate is evaluated by using a three index values of a resolution index value T, a reflection image diffusiveness index value R, and a sparkle index value S, the following conditions are satisfied: the resolution index value T≤0.2, the reflection image diffusiveness index value R≥0.2, and the sparkle index value S≤60.
