A twisted hybrid aligned nematic orientation turns to a TN orientation, that is a quasi TN (Q-TN), by weakening the anchoring on only one side of the substrate. The driving voltage can be reduced in the Q-TN. The relationship between elastic constants, anchoring strengths and electro-optical properties are numerically clarified when using the spontaneous 90° LC cell.
