1. A liquid crystal display panel having a display mode that is a VA mode, comprising:
a plurality of rectangular-shaped pixels;
a first substrate section including a first substrate and pixel electrodes;
a liquid crystal layer provided on the first substrate section, the liquid crystal layer containing liquid crystal molecules; and
a second substrate section provided on the liquid crystal layer, the second substrate section including a second substrate and a counter electrode, wherein
each of the plurality of rectangular-shaped pixels includes a first domain, a second domain, a third domain, and a fourth domain arranged along a longitudinal direction of the pixel,
when a direction orthogonal to the longitudinal direction of the pixel is defined as a transverse direction of the pixel and an azimuth flush with the transverse direction of the pixel is defined as 0°, an alignment azimuth of the liquid crystal molecules in the second domain is substantially 225° and an alignment azimuth of the liquid crystal molecules in the third domain is substantially 45°; or the alignment azimuth of the liquid crystal molecules in the second domain is substantially 315° and the alignment azimuth of the liquid crystal molecules in the third domain is substantially 135°,
the first domain, the second domain, the third domain, and the fourth domain are arranged in one row along the longitudinal direction of the pixel in this order, and
each pixel electrode includes
a first pixel electrode portion facing the first and second domains in a thickness direction of the pixel electrode,
a second pixel electrode portion facing the third and fourth domains in the thickness direction of the pixel electrode,
a bridging portion being provided between the first pixel electrode portion and the second pixel electrode portion and linking together the first pixel electrode portion and the second pixel electrode portion,
a first recess being provided at one side along a width direction of the pixel electrode, the first recess extending toward the bridging portion along the width direction of the pixel electrode and being located between the first pixel electrode portion and the second pixel electrode portion, and
a second recess being provided at another side along the width direction of the pixel electrode, the second recess extending toward the bridging portion along the width direction of the pixel electrode and being located between the first pixel electrode portion and the second pixel electrode portion.
