What is the detailed explanation of the limited viewing angle experienced with LCD displays? Since LCD relies on polarization, it seems to me that with reflective displays (i.e. ones without built-in light source, using onyl reflected external light) the amount of light reflected from the display depends heavily on the viewing angle, since the reflected light is polarized, so for some angles no light will be reflect at all etc. (as in Brewster's angle). However, how you explain this in backlit displays?
