Abstract
A liquid crystal display device of the present invention includes: a first substrate including a pair of counter electrodes; a second substrate including a pixel electrode and a common electrode; and a liquid crystal layer that includes liquid crystal molecules aligned horizontally with the substrates. The liquid crystal display device is configured to perform display in any of multiple display modes. The multiple display modes include: a first display mode of performing display in a first state where an alternating-current voltage is applied at a first frequency between the pair of counter electrodes; and a second display mode of performing display in at least one of a second state where no voltage is applied between the pair of counter electrodes, or a third state where an alternating-current voltage is applied at a second frequency that is higher than the first frequency between the pair of counter electrodes.
