Abstract
A display apparatus includes a first display plate, a first electrode and a second electrode disposed on the first display plate, a second display plate, a third electrode disposed on the second display plate, and a liquid crystal layer disposed between the first display plate and the second display plate. The liquid crystal layer includes liquid crystal molecules oriented substantially perpendicular to the first display plate and the second display plate in a state where no voltage is applied to the first to third electrodes. When a display state is to change from a first grayscale in a first grayscale region to a second grayscale in a second grayscale region, a return voltage, which is larger than the sum of the common voltage and a threshold voltage of the liquid crystal molecules, is applied to the first electrode and the second electrode for at least a specified period before the first drive voltage and the second drive voltage, which correspond to the second grayscale, are applied to the first electrode and the second electrode.
