ABSTRACT:
A polarization control system which includes an E-type polarizer and therefore can provide excellent dark state at a wide azimuth and viewing angle. Further, the polarization control system includes a viewing angle control element for controlling a traveling direction of light which has passed through the E-type polarizer and therefore can provide excellent bright state at a wide azimuth and viewing angle. Further a display device is disclosed including such a polarization control system. The polarization control system is a polarization control system including a plurality of polarizers, wherein the polarization control system includes an E-type polarizer and a viewing angle control element, and the viewing angle control element controls a traveling direction of light which has passed through the E-type polarizer.
