An array substrate (10) of the present invention includes: an insulating substrate; a plurality of scanning lines (2) on the insulating substrate; a plurality of data lines (1) each disposed so as to intersect the plurality of scanning lines (2) on the insulating substrate; picture element electrodes (13) each formed in a substantially rectangular shape, the picture element electrodes (13) each being connected, via a switching element (5), to a corresponding scanning line (2) and a corresponding data line (1), the picture element electrodes (13) each having a long side disposed along a direction in which the plurality of scanning lines (2) are extended and a short side disposed along a direction in which the plurality of data lines (1) are extended, the picture element electrodes (13) each having cut sections (13a) formed by cutting two corners of each of the picture element electrodes, the cut sections being formed so as to serve as alignment dividing means. This makes it possible, regarding an MVA liquid crystal display device, to easily ensure a sufficient process yield as well as improving display quality by ensuring a sufficient aperture ratio in each one pixel.
