The liquid crystal display device includes a pixel structure provided with a large wall formed along a long side of a pixel with a rectangular plane, a small wall formed at a center of the pixel and extending in the same direction as the large wall, a wall electrode formed on a wall surface of the large wall, a plane electrode formed between the small and large walls, in which the wall electrode and the plane electrode form a pixel electrode, and a common electrode formed on a surface of the small wall. The large wall has a part with an increased thickness at an end part of the pixel. The wall electrode is bent toward the center of the pixel. This structure prevents decrease of reverse twist of liquid crystal at an end part of the pixel as well as generation of domain, thus improving transmittance of the screen.
