That's a good question. I don't think there's any liquid in the sense of
some chemical suspended in some solvent. I think "liquid crystal" refers
to the interesting property of a certain class of compounds which can
exist in both an amorphous liquid state as well as a crystaline state
(e.g., in the presense of heat or electricity). I remember playing with
sheets of the stuff when I was a kid (around the time liquid crystal "mood
rings" were in vogue), but I have no idea which compounds are used in LCD
displays. Some inert polymer, I'd guess.
