Laminated glass
A laminated glass includes a first glass plate on a vehicle exterior side, a second glass plate on a vehicle interior side, an intermediate film disposed between the first and second glass plates, a first shielding layer disposed in a peripheral section on an interior surface of the second glass plate, a film disposed between the first and second glass plates, the film extending, in a plan view, in a region overlapping the first shielding layer, and an information-acquisition-area positioned within an opening provided through the first shielding layer and the film, the information-acquisition-area allowing a sensor to obtain information, and wherein a portion of the laminated glass in which the film is disposed and the first shielding layer is not disposed has a visible light reflection of 8% or more, or a diffuse reflection of 9% or more.

a film disposed between the first and second glass plates, and extending, in a plan view, in a region overlapping the first shielding layer; and
an information-acquisition-region positioned within an opening provided through the first shielding layer and the film, the information-acquisition-region allowing a sensor to obtain information, and
wherein a portion of the laminated glass in which the film is disposed and the first shielding layer is not disposed has a visible light reflectivity of 8% or more, or a diffuse reflectivity of 9% or more, and
wherein in the opening, an edge of the film retreats, in a plan view, with respect to an edge of the first shielding layer, and a retreat distance α of the edge of the film with respect to the end of the first shielding layer is 1 mm or more.
2. The laminated glass according to claim 1 , further comprising a second shielding layer disposed in a peripheral section on an interior surface of the first glass plate, and
wherein an edge of a shielding layer used as a reference in defining the retreat distance α is an edge of a shielding layer positioned closer to a center of the opening, from among the first shielding layer and second shielding layer.
3. The laminated glass according to claim 2 , wherein the second shielding layer is the shielding layer positioned closer to the center.
4. The laminated glass according to claim 1 , wherein a retreat distance α top with respect to a top side of an outer peripheral section of the information-acquisition-region is 1 mm or more when the laminated glass is mounted on a vehicle.
5. The laminated glass according to claim 1 , wherein a retreat distance α bottom with respect to a bottom side of an outer peripheral section of the information-acquisition-region is 1 mm or more when the laminated glass is mounted on a vehicle.
6. The laminated glass according to claim 1 , wherein a retreat distance α side with respect to left and right sides of an outer peripheral section of the information-acquisition-region is 1 mm or more when the laminated glass is mounted on a vehicle.
7. The laminated glass according to claim 1 , wherein a thickness of the film is 25 μm or more to 200 μm or less.
8. The laminated glass according to claim 1 , wherein, in a plan view, an outer periphery of the information-acquisition-region is entirely surrounded by at least one shielding layer.
9. The laminated glass according to claim 1 , wherein, in a plan view, a part of an outer periphery of the information-acquisition-region is surrounded by at least one shielding layer, and wherein a remaining part of the outer periphery is not surrounded by the shielding layer.
10. The laminated glass according to claim 1 , wherein the laminated glass includes a display region for HUD (Head-Up Display).
11. The laminated glass according to claim 1 , wherein the film is a p-polarized light reflection film.
12. The laminated glass according to claim 1 , wherein the information-acquisition-region has a curved surface.
13. The laminated glass according to claim 1 , wherein an installation angle of the laminated glass with respect to a horizontal plane of the vehicle is 15 degrees or more to 35 degrees or less.
14. A laminated glass comprising:
a first glass plate on a vehicle exterior side;
a second glass plate on a vehicle interior side;
an intermediate film disposed between the first and second glass plates;
a first shielding layer disposed in a peripheral section on an interior surface of the second glass plate;
a film disposed between the first and second glass plates, and extending, in a plan view, in a region overlapping the first shielding layer; and
an information-acquisition-region positioned within an opening provided through the first shielding layer and the film, the information-acquisition-region allowing a sensor to obtain information, and
wherein a portion of the laminated glass in which the film is disposed and the first shielding layer is not disposed has a visible light reflectivity of 8% or more, or a diffuse reflectivity of 9% or more, and
wherein in the opening, an edge of the first shielding layer retreats, in a plan view, with respect to an edge of the film, and a retreat distance β of the edge of the first shielding layer with respect to the end of the film is 1 mm or more.
15. The laminated glass according to claim 14 , wherein a retreat distance β top with respect to a top side of an outer peripheral section of the information-acquisition-region is 1 mm or more when the laminated glass is mounted on a vehicle.
16. The laminated glass according to claim 14 , wherein a retreat distance β bottom with respect to a bottom side of an outer peripheral section of the information-acquisition-region is 1 mm or more when the laminated glass is mounted on a vehicle.
