摘要：

The authors have observed highly circularly polarized electroluminescence from organic light-emitting diodes (OLEDs) using wide-band reflector consisting of three-layered left-handed polymeric cholesteric liquid crystal (PCLC) films. By simply attaching the wide-band reflective PCLC reflector to a conventional OLED, the authors obtained a high degree of circular polarization, i.e., the ratio of brightness between right- and left-handed circularly polarized electroluminescences is over 10 over the whole emission band.
