I don't think there was liquid in an eInk display like in an LCD (l=liquid).
And, I'm wrong:
The principal components of electronic ink are millions of tiny microcapsules, about the diameter of a human hair. In one incarnation, each microcapsule contains positively charged white particles and negatively charged black particles suspended in a clear fluid.
So, what you say makes perfect sense.
