ラビング処理を施したPEDOT/PSS膜によるネマティック液晶の配向

抄録

The poly (3,4-ethylenedioxythiophene) doped with poly (4-styrenesulfonate) (PEDOT/PSS) have electrical conductivity and flexibility, and is expected to supersede the ITO electrode. We have been developing a low-cost display using rubbed PEDOT/PSS films. In this study, we report about basic characteristics of Liquid Crystal (LC) alignment on the PEDOT/PSS film. Here, sample LC cells of homogeneous mode with the rubbed PEDOT/PSS electrode were fabricated, then, the LC alignment parallel to the rubbing directions was observed. However, transmittance vs. applied voltage characteristics was shifted approx. +1 V, and the degradation of electrical resistance was observed. From this result, the PEDOT/PSS has a possibility to affect the damage to the LC materials.
