Does PDLC smart glass become opaque?
No, the correct term is translucent, since light still gets through, albeit scattered in many directions. The glass would be opaque only if the light was blocked or absorbed.
Yes, smart glass/film is a rear projector screen with wide viewing angles. Even from the side one can enjoy clear, beautiful images and also in bright locations with high functional projectors.

No, the transmittance (level of transparency) of the PDLC can be varied from 0% in the OFF state up to any value you want until you reach the maximum transmittance (normally 70% or 80%). This is done by simply altering the voltage from 0 VAC up to 70VAC, which is typically the maximum recommended voltage. This can be done electrically with a variable isolating transformer, or electronically with a switched-mode smart glass dimmer.
Smart glass is a laminated glass comprising 2pcs of glass sandwiched in between by an EVA/PVB interlayer.
The smartness of PDLCs is a result of its ability to change its transparency (technically called the transmittance) when an electrical stimulus is applied to it. This is normally by way of an alternating voltage, which exerts an alternating electric field across the PDLC material.
Nevertheless, the PDLC is only as smart as the control system which stimulates the change, which can be driven by a push button switch, a light sensor, or a building automation system.
Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.
