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 E.sub.1 [MPa], a relationship between ts and E.sub.1 satisfies E.sub.1×ts.sup.3≥500.

The invention is a robust lensless instrument cluster configured for installation in a vehicle. The instrument cluster comprises an outer case, a PCB and lighting structure, an inner frame, an optical bonding assembly, halo lighting portions, a seamless display comprising tell-tale indicators and gauges, and an outer visor. The instrument cluster further comprises a plurality of LEDs for compartmentalized and indirect lighting of the tell-tale indicators on the seamless display and the halo lighting portions around the edges of the seamless display. Because the instrument cluster is lensless and otherwise exposed to the environment, it comprises a seal system to prevent the ingress of water and dust into the interior components. The seal system can also eliminate the risk of mura in the optical bonding assembly.
