Polarizers are responsible for creating the image that is displayed on an LCD. The science of how light is polarized through the LCD can be a bit confusing. Simply stated, the light dispersed through the LCD is not actually created by the liquid crystals themselves. Ambient light is actually reflected off the relective rear polarizer back out the front of the LCD. The image that is seen with the naked eye is the light that is blocked by the front polarizer. Without these polarizers, the LCD would be completely transparent, with no image displayed.
