Any LCD could do this. They're innately transparent. It just never leaves the prototype / floor-model stage, because it's kinda stupid.
One egregious example was an admittedly large screen, set vertically, pushing the idea it was "holographic telepresence." A guy walked in front of a camera and his flat image appeared vaguely three-dimensional because it hovered in front of, essentially, a well-lit bathtub.
This is more expensive, significantly smaller, and doesn't give the impression the guy might step out of the thing.
