Abstract
During a drive period, luminance momentarily decreases when the value β(A−B) is positive and momentarily increases when the value β(A−B) is negative. When the luminance increases during a pause period in accordance with the balance in time constant between an alignment film and a liquid crystal material that are included in a pixel forming portion, primary and secondary parasitic capacitances are adjusted so as to set the value β(A−B) to be negative.
