1. A display device comprising:
a first substrate;
a second substrate opposed to the first substrate; and
a liquid crystal layer located between the first substrate and the second substrate, wherein
the first substrate includes a first common electrode, a second common electrode, a pixel electrode, a scanning line, and a signal line,
the scanning line is formed to extend in a first direction,
the signal line is formed to extend in a second direction,
the first common electrode includes a shaft portion extending in the second direction, a first branch portion extending in the first direction from the shaft portion, and a second branch portion extending in the first direction from the shaft portion,
a first opening surrounded by a pair of the scanning lines and a pair of the signal lines, and a second opening surrounded by a pair of the scanning lines and a pair of the signal lines and provided at an interval from the first opening in the second direction are provided,
the second common electrode is disposed from the first opening to the second opening and overlaps the first common electrode,
the first common electrode and the second common electrode has the same electric potential,
the first branch portion overlaps the pixel electrode and the first opening, and
the second branch portion overlaps the scanning line between the first opening and the second opening, and
the pixel electrode is located between the first common electrode and the second common electrode in cross-sectional view.
