The present invention provides a liquid crystal display device in a new display mode that is based on the horizontal alignment capable of giving a wide viewing angle and that can achieve high speed response. The liquid crystal display device includes: a first substrate that includes a pair of electrodes; a second substrate that includes a pixel electrode and a common electrode; and a liquid crystal layer that contains liquid crystal molecules aligned horizontally, at least one of the pair of electrodes including a first linear portion that extends in a first direction, at least one of the pixel electrode and the common electrode including a second linear portion that extends in a second direction intersecting the first direction, the liquid crystal molecules being aligned in a direction perpendicular or parallel to the first direction in a first display state in which voltage is applied between the pair of electrodes but voltage is not applied between the pixel electrode and the common electrode, the liquid crystal molecules being aligned in a direction different from the alignment direction of the first display state, in a second display state in which voltage is applied between the pair of electrodes and voltage is applied between the pixel electrode and the common electrode.
