I was under the impression that a liquid crystal is an organic molecule 
dissolved in water. So I'm guessing changing the concentration is going 
to fairly radically alter the optics of the material, and possibly even 
turn it from a liquid crystal into a plain ordinary liquid.

Then again, I don't design LCDs for a living. ;-)
