Not to be condescending or anything, but you did rotate it, right? ;)
I know, I know, the reflections don't always completely disappear, but they typically diminish greatly.
The simplest way to explain the science is that ordinary light is coming at you in two waves, one waveform horizontal, the other vertical. A polarising lens, or piece of plastic from a calculator, blocks one or the other depending on its orientation.
There are the odd waveforms though that could be in any diagonal orientation, so the polarising lens doesn't always work 100%, but it usually does a decent job.
A circular polariser works on the same principle as the thin sheet of polarising plastic on the faces of pocket calculators, but the plastic polarising the LCD screen has the advantage that the waveform passing through is generated in only two basic orientations, horizontal and vertical. You can check this out for yourself by simply looking through one at an LCD screen, like that on a laptop or LCD monitor, and rotating it.
Sorry if I'm rambling.
