In this liquid crystal display device, a plurality of pixelsare arranged in a display region. The liquid crystal display device comprises a first substratein which a pixel electrodehaving slitsis provided, a second substrate disposed face to the first substrate, a liquid crystal layercontaining liquid crystal molecules that have negative dielectric anisotropy, a first alignment film, and a second alignment film. The slitsare positioned in each alignment region of a plurality of alignment regions in the pixels, and have oblique slit parts extending in an oblique direction with respect to sides of the pixels. The angle γ formed by the direction in which the oblique slit parts extends and a liquid crystal projection direction is 15 degrees or more and 85 degrees or less.

Liquid crystal display device

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.
