Laminated glass

1. A laminated glass comprising:

a vehicle-outer side glass plate;

a vehicle-inner side glass plate;

an interlayer film disposed between the vehicle-outer side glass plate and the vehicle-inner side glass plate; and

a first film disposed between the interlayer film and one of the vehicle-outer side glass plate and the vehicle-inner side glass plate, the first film being bonded by a first adhesive layer to the one of the vehicle-outer side glass plate and the vehicle-inner side glass plate,

wherein the first film is disposed in at least a part of a display area configured to display information by reflecting an image projected from an inside of a vehicle, and

wherein a thickness of the first adhesive layer is 6 μm or more, and is less than 25 μm.

2. The laminated glass according to claim 1 , wherein the thickness of the first adhesive layer is 6 μm or more and 20 μm or less.

3. The laminated glass according to claim 2 , wherein the thickness of the first adhesive layer is 6 μm or more and 15 μm or less.

4. The laminated glass according to claim 1 , wherein the first film is a visible light control film configured to reflect the image projected from the inside of the vehicle.

5. The laminated glass according to claim 1 , wherein a relationship between the thickness, denoted as t 1 in units of mm, of the first adhesive layer and a Young's modulus, denoted as E 1 in units of N/mm 2 , of the first adhesive layer satisfies E 1 t 1 3 ≥5×10 −12 .

6. The laminated glass according to claim 1 , further comprising a second adhesive layer disposed between the interlayer film and the first film.

7. The laminated glass according to claim 6 , wherein a relationship between a thickness, denoted as t 2 in units of mm, of the second adhesive layer and a Young's modulus, denoted as E 2 in units of N/mm 2 , of the second adhesive layer satisfies E 2 t 2 3 ≥5×10 −12 .

8. The laminated glass according to claim 6 , wherein a thickness of the second adhesive layer is 1 μm or more, and is less than 25 μm.

9. The laminated glass according to claim 8 , wherein the thickness of the second adhesive layer is 1 μm or more and 20 μm or less.

10. The laminated glass according to claim 9 , wherein the thickness of the second adhesive layer is 1 μm or more and 15 μm or less.

11. The laminated glass according to claim 6 , wherein a summation of the thickness of the first adhesive layer and a thickness of the second adhesive layer is 7 μm or more, and is less than 25 μm.

12. The laminated glass according to claim 1 , wherein when the laminated glass is attached to the vehicle, a radius of curvature in a vertical direction of the display area is 4000 mm or more and 20000 mm or less, and a radius of curvature in a horizontal direction of the display area is 1000 mm or more and 10000 mm or less.

13. The laminated glass according to claim 1 , wherein a thickness of the first film is 25 μm or more and 200 μm or less.

14. The laminated glass according to claim 1 , wherein the first film is a P-polarized light reflection film, and

in a state where the first film is sealed in the laminated glass, a reflectivity of the first film with respect to P-polarized light with an incidence angle being Brewster's angle is 5% or more.

15. The laminated glass according to claim 1 , wherein the first adhesive layer is located at a vehicle-inner side with respect to the first film, and

a difference in a principal refractive index of the first adhesive layer in an in-plane direction with respect to light having a wavelength of 550 nm is within 0.1.

16. The laminated glass according to claim 1 , wherein a field of view of the image projected is 4 deg×1 deg or more.
