What is a Liquid Crystal?
A liquid crystal is a hybrid between (i) a liquid which flows like a fluid and (ii) a crystal which is normally found as a solid, exhibiting short- or long-range symmetry.
Yes, smart glass/film can be used in wet areas such as bathrooms. The edges of smart glass/film are are sealed with a non-acid silicone gel that prevent any contact with water.

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.
Smart glass works via electrical signal through activation of switches, sensors etc. Liquid crystal molecules turn to allow light to pass through and glass becomes transparent. It is opaque when not activated.
The liquid crystals change their refractive index in relation to the isotropically transparent polymer in which they are immersed, thereby creating multiple step boundaries throughout the PDLC.
It is this change in refractive index at each boundary which causes light to change course. Since the PDLC material contains millions of liquid crystals, each with a boundary facing a slightly different way, the light is scattered in many directions.
The net effect is to hide whatever is behind the PDLC smart glass.
