This liquid crystal display device has a plurality of pixels. Each pixel in the plurality of pixels includes first to fourth alignment regions; these first to fourth alignment regions are arranged in the longitudinal direction of the pixels, and the difference between any two alignment orientations in the first to fourth alignment regions is approximately equal to an integer multiple of 90 degrees. Of the pre-tilt angles defined by a first alignment film and a second alignment film in each of the first to fourth alignment regions, one pre-tilt angle is less than 90 degrees and the other pre-tilt angle is substantially 90 degrees. The optical alignment film is formed using a polymer having an optical alignment group in the side chain, and the content of the optical alignment group in the side chain of the polymer is less than 1.1 mmol/g.
