I think you could improve your question by saying which parts you do and don't understand.

comment Liquid crystal shutter with >90% transmission?
A suggestion: as I mentioned in my answer, so much engineering goes into these things that nobody here is going to be able to help you with manufacturing strategies. Instead, why not partner with that research group at NCSU? That would benefit you both (science funding always seems to flow more readily if the funding agencies see that you are partnering with industry.)

comment Liquid crystal shutter with >90% transmission?
The second paper describes an optical filter, not a shutter. The first paper works in a different way than you describe above - instead of blocking the light with crossed polarizers and transmitting it with parallel polarizers, it doesn't block any light at all. Instead of blocking, it diverts it to the side, outside of an arbitrarily defined "viewing angle". Figure 2 of that paper is a fairly clear illustration of this.

comment A problem concerning the change of temperature and spectrum of a filament
Could be a crappy digital camera that does not reproduce colors properly? Or the color profile got changed somehow during editing?

comment formula for transparency of very thin film of metal
For a given wavelength, you need the complex permittivity or complex refractive index of aluminum and the refractive indices of the materials on either side of the aluminum film. (See refractiveindex.info). I'll post a more extensive explanation if I have time tomorrow and nobody else has yet.
