Abstract

We demonstrated a highly polarized organic electroluminescence device through enhancing an orientational ordering of the conjugate polymer. The highly ordered state of the conjugate polymer and the resultant high polarizability were obtained by improving azimuthal anchoring energy through the optimal rubbing condition of a polyimide underlying the emitting layer. The polarized OLED was adapted to the twisted nematic liquid crystal cell as a backlight unit and tested the electro-optic characteristics.
