the plurality of slits includes:
a plurality of first slits, each extending and forming an acute angle in a clockwise direction with respect to the pixel short-hand direction, and
a plurality of second slits, each extending and forming an acute angle in a counterclockwise direction with respect to the pixel short-hand direction,
the first electrode includes:
a first region in which the plurality of first slits is formed, and
a second region in which the plurality of second slits is formed, the second region being adjacent to the first region along the pixel longitudinal direction,
in a plan view, each of the plurality of source wiring lines is bent at a position corresponding to a boundary between the first region and the second region of the first electrode,
an outer edge of each of the plurality of slits includes a pair of long sides and a pair of short sides,
the pair of short sides is respectively located at both ends of each of the plurality of slits in the pixel short-hand direction,
