Abstract
Polarized light emission from polymer light emitting diodes (LEDs) is one step towards improved sources of background illumination for effic ient liquid crystal displays. It is demonstrated that the fabrication of organic LEDs based on poly(p-phenylene)s by the Langmuir-Blodgett t echnique enables the polarization of the emitted light to be controlle d. The ratio of the intensity of light polarized parallel and perpendi cular to the dipping direction is the highest reported so far. Photolu minescence and electroluminescence spectra are presented and discussed .
