According to one embodiment, a liquid crystal display device includes a first substrate including a cross-shaped pixel electrode which includes a main pixel electrode and a sub-pixel electrode, and a second substrate including a common electrode which includes main common electrodes and sub-common electrodes. A first horizontal inter-electrode distance between the main pixel electrode and the main common electrode is less than a second horizontal inter-electrode distance between the sub-pixel electrode and the sub-common electrode and is greater than a vertical inter-electrode distance between the main pixel electrode and the main common electrode.
