You forget that there are at least three polarizers at work in an LCD;
the polarizer, the liquid crystal material, and the analyzer. If each
polarizer was 50% transmissive, the result would be 12.5% light
transmission available for the filters.
You seem to be on a different tangent with polarization. I was
referring to the efficiency with which the spectrum emitted
can stimulate the three color receptors independently.
As for you calculation, I'm not following it. While a polarizer
might reduce the transmission of unpolarized light by 50%, surely
subsequent polarizers with the same orientation will cause
much lower losses.
