Really? I thought it might just make the edges go a bit fuzzy or
something...

Something to do with how the moisture gets absorbed by the LC, of course it
starts from the edges wherever there is the "leak", but it quickly spreads
across the whole panel until you don't get any picture. I suspect the water
molecules are severely impacting on the electrical/optical properties of the
LC, and given that you're talking about a thickness of a couple of microns
you don't need many water molecules to mess things up!

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. ;-)
