Abstract

We proposed wideband antireflective circular polarizer for realizing a true black state in all viewing directions in organic lightemitting- diode displays (OLEDs). Present commercialized wideband circular polarizer consisted of a half wave and a quarter wave plates having the refractive index parameter (N_z) of 1.5 in both films exhibits light leakage in the oblique viewing directions, deteriorating image quality of a black state. We evaluated N_zs of both films and proposed a new wideband antireflective circular polarizer with a perfect dark state in all viewing directions with N_z = 0.5 in both plates, which will greatly improve image quality of OLEDs.
