Though transmittance dependency of DC offset voltage that relate to image sticking made a quadratic function, its bottom position and flicker minimum DC offset voltage depend on gray level due to flexoelectric effect. We demonstrated influence of flexoelectric effect changes depending on slit electrode width and black matrix width.
