1. A liquid crystal display panel, comprising:
a plurality of pixels, each including a pixel electrode provided above a main surface of a substrate, a common electrode provided above the main surface of the substrate, and a liquid crystal that rotates in-plane of the main surface of the substrate due to voltage applied by the pixel electrode and the common electrode, wherein
the pixel electrode includes a base line electrode and linear electrodes branched from the base line electrode,
the linear electrodes extend to both sides of the base line electrode across the base line electrode, and one end of each linear electrode is not connected to the base line electrode, and
when an initial alignment direction of the liquid crystal for which dielectric anisotropy is positive, or a direction perpendicular to the initial alignment direction of the liquid crystal for which dielectric anisotropy is negative is defined as a predetermined first direction,
at a boundary between pixels, of the plurality of pixels, that are adjacent to each other, a boundary line between the adjacent pixels, the linear electrodes, and an end side of the each linear electrode at the one end not connected to the base line electrode are inclined with respect to the predetermined first direction, and inclining directions with respect to the predetermined first direction of the boundary line, the linear electrodes, and the end side are identical.
