摘要：

The transient currents were observed in nematic liquid crystal (LC) cells when the polarity of the applied square wave voltage was reversed. The magnitude of these currents were shown to increase when the used LCs have a tendency to form dimers and the orientation films have a high electrical polarization. The origin of the transient currents is explained by assuming the switching of LC layers associated with the bilayers made of decomposed monomers adsorbed on the orientation films. The origin of the crosstalk appearing in the STN dot matrix LCDs is discussed in conjunction with the decomposition of dimers in the surface alignment region. © 1990 IOP Publishing Ltd.
