Abstract: The visibility of the external scene from the inside of the transmissive transparent screen when the video image is not displayed and the visibility of the video image from the outside when the video image is displayed are satisfied.
In a video image display system comprising a projection device 100 and a transmissive transparent screen 1 having a first surface and a second surface on the opposite side of the first surface, having a visible light transmittance of at least 5[%], and displaying video images projected from the projection device 100 installed on the first surface side, as video images visible to an observer on the second surface side, the following formula 1 is satisfied:

−1.5≤ln(((B/A)/I)×G)≤3.9  Formula 1



in the formula 1, A is the projection area [m2] of the projection device 100, B is the luminous flux [lm] projected onto A by the projection device 100, I is the ambient illuminance [lx] at the side of the second surface, and G is the screen gain of the transparent screen 1.

Abstract: Laminated glass for a vehicle includes a vehicle-interior side glass plate, a vehicle-exterior side glass plate, an interlayer film that bonds the vehicle-interior side glass plate and the vehicle-exterior side glass plate, and a structure sealed in the interlayer film. The interlayer film includes a first interlayer film bonded to the vehicle-interior side glass plate, a second interlayer film bonded to the vehicle-exterior side glass plate, and a third interlayer film located between the first interlayer film and the second interlayer film to enclose an outer periphery of the structure. Where a film thickness of the first interlayer film or the second interlayer film, whichever is thinner, is denoted as ti, and a thickness of the structure is denoted as ts, ti/ts≥0.4 is satisfied. Where a flexural modulus of the structure is denoted as E1 [MPa], a relationship between ts and E1 satisfies E1×ts3≥500.
