We report an analysis of the optical performance degradation in an ion-doped liquid crystal cell. When an electric field is applied to the cell for a long time, the optical performance becomes non-uniform, and the haze value in the opaque state decreased. Based on the measurement of the optical and physical characteristics, we estimated that the degradation is caused by ionic materials.
