Changes in the surface properties of Indiumoxide electrodes in liquid crystal cells with homeotropically aligned doped nematics were investigated when a dc voltage was applied to clarify the relationships between those changes and alignmental deterioration. Contact angle measurements showed that only the energy of the cathode surface increased. Auger spectra suggest that the changes in surface energy are caused by a reduction of In_2O_3. The changes apparently cause the film on the surface of the electrode to break away from the surface. The deterioration process apparently occurred as follows. First, the reduction of In_2O_3 occurred on the cathode and the surface film broke away. This caused the surface energy to increase and that initiated alignmental deterioration.
