We review the electron transport in both smectic and discotic liquid crystals with the updated experimental results, and discuss the ambipolar carrier transport in these materials. We indicate that the intrinsic nature of charge carrier transport in liquid crystals is probably ambipolar, in which both electronic and ionic charges are transported basically irrespective of their polarity, and that the ionic transport in these liquid crystals is extrinsic and induced by photo-ionization of chemical impurities. Furthermore, we discuss the importance of this unique features of charge carrier transport in the liquid crystals in the future development of new optoelectronic device applications that cannot be achieved with conventional organic semiconductors.
