Liquid crystal display device

A liquid crystal display device in which a plurality of pixels are arranged in a display region, comprising:

• a first substrate, on which a pixel electrode having a slit is provided;
• a second substrate, arranged to face the first substrate;
• a liquid crystal layer, disposed between the first substrate and the second substrate and contains liquid crystal molecules having negative dielectric anisotropy;
• a first alignment film, formed on the first substrate;
• a second alignment film, formed on the second substrate;
• a first polarizing plate, disposed on an opposite side to the liquid crystal layer with the first substrate therebetween;
• and
• a second polarizing plate, disposed on an opposite side to the liquid crystal layer with the second substrate therebetween,
• wherein at least one of the first alignment film and the second alignment film is a photo-alignment film,
• wherein each pixel in the plurality of pixels has a plurality of alignment regions in which alignment orientations of liquid crystal molecules are different from each other when a voltage is applied,
• wherein the slit is arranged in each alignment region in the plurality of alignment regions and has an oblique slit part formed to extend in an oblique direction with respect to each side of the pixel, and
• wherein, in a plan view, a transmission axis of the first polarizing plate and a transmission axis of the second polarizing plate are orthogonal to each other, and
• wherein, when an axial direction of the transmission axis of the first polarizing plate is defined as 0 degrees and an axial direction of the transmission axis of the second polarizing plate is defined as 90 degrees, a liquid crystal projection direction is 0 degrees or more and 30 degrees or less in each of the plurality of alignment regions, wherein the liquid crystal projection direction is a direction in which a longitudinal direction of liquid crystal molecules present in the vicinity of the center of the liquid crystal layer in a thickness direction when no voltage is applied is projected onto the first substrate, and an angle formed by a direction in which the oblique slit part extends and the axial direction of the transmission axis of the first polarizing plate is 45 degrees or more and 85 degrees or less in each of the plurality of alignment regions.
