It seems to basically just have a huge number of very dense pixels, and in front it has some tiny lenses that direct each pixel at a different angle.
Presumably there's a maximum distance you can view from because the further you get away from the display, the smaller the angle between your eyes. I would guess it's no coincidence that Google has set it up as a booth with a back wall that would ensure you keep close enough:
