Abstract
Transflective display device has an optical waveguide commonly known as a light guide. The guide includes areas having a chiral nematic structure which splits light coming in from aside into two light beams having a mutually opposite circular polarization. Polarization splitting is achieved at the interface of the areas having the chiral nematic structure.
