1. A liquid crystal display apparatus comprising:
a first substrate and a second substrate positioned opposite each other; and
a liquid crystal layer of a vertical alignment type interposed between the first substrate and the second substrate, wherein:
the liquid crystal display apparatus has a plurality of pixels,
the first substrate includes a pixel electrode provided in each of the plurality of pixels, and a first alignment film is provided between the pixel electrode and the liquid crystal layer,
the second substrate includes a counter electrode opposite the pixel electrode, and a second alignment film provided between the counter electrode and the liquid crystal layer,
each of the plurality of pixels includes a first liquid crystal domain, a second liquid crystal domain, a third liquid crystal domain, and a fourth liquid crystal domain, each of the first to fourth liquid crystal domains having a reference alignment direction defined by the first alignment film and the second alignment film, and the first to fourth liquid crystal domains having respectively different reference alignment directions,
a longitudinal direction and a transverse direction of each of the plurality of pixels respectively define a pixel longitudinal direction and a pixel transverse direction of that pixel, and the reference alignment directions of the first liquid crystal domain, the second liquid crystal domain, the third liquid crystal domain, and the fourth liquid crystal domain respectively define a first direction, a second direction, a third direction, and a fourth direction,
the first direction, the second direction, the third direction, and the fourth direction, each makes an angle, which is essentially equal to an odd multiple of 45°, with respect to the pixel transverse direction of each pixel,
the first liquid crystal domain, the second liquid crystal domain, the third liquid crystal domain, and the fourth liquid crystal domain are arranged in this order along the pixel longitudinal direction of the pixel,
the second direction and the third direction are respectively essentially the 135° direction and essentially the 315° direction, or are respectively essentially the 45° direction and essentially the 225° direction, wherein an azimuth angle of the pixel transverse direction is defined as 0°;
the pixel electrode includes:
a first slitted region which is a region corresponding to the first liquid crystal domain, and in which a plurality of first slits extending essentially in parallel to the first direction is formed,
a second slitted region which is a region corresponding to the second liquid crystal domain, and in which a plurality of second slits extending essentially in parallel to the second direction is formed,
a third slitted region which is a region corresponding to the third liquid crystal domain, and in which a plurality of third slits extending essentially in parallel to the third direction is formed,
a fourth slitted region which is a region corresponding to the fourth liquid crystal domain, and in which a plurality of fourth slits extending essentially in parallel to the fourth direction is formed, and
a boundary region located between the second slitted region and the third slitted region, and
the boundary region includes:
n boundary slits, where n is an integer equal to or greater than 3, each boundary slit extending essentially in parallel to the pixel transverse direction, the n boundary slits being arranged along the pixel transverse direction,
(n-1) first bridging portions each being located between two adjacent boundary slits among the n boundary slits, the (n-1) first bridging portions interconnecting the second slitted region and the third slitted region, and
(n-2) dent patterns each being located between two adjacent first bridging portions, among the (n-1) first bridging portions, and each including a first dent formed so as to be dented into the second slitted region from a boundary slit that is located between the two first bridging portions, and a second dent formed so as to be dented into the third slitted region from the boundary slit that is located between the two first bridging portions.
