This chapter describes a basic overview of electrical measurements such as voltage holding ratio (VHR), ion impurity, residual DC (RDC) voltage and capacitance- voltage (C-V) for elastic constant measurement of liquid crystals. Furthermore, ion impurity measurement in a thin film transistor liquid crystal display (TFT-LCD) panel is also described to find a root cause of image-sticking phenomena.
