Claim 0:
1. A liquid crystal display device comprising:
an array substrate including an insulating substrate, source lines arrayed in a first direction at an interval, gate lines arrayed in a second direction crossing the first direction at an interval, an insulating film which is a single film and has a first surface and a second surface opposed to the first surface, a common electrode which is in contact with the first surface, a first pixel electrode which is in contact with the second surface of the insulating film, a second pixel electrode which is in contact with the second surface of the insulating film, and a first alignment film which is in contact with the first pixel electrode and the second pixel electrode;
a counter-substrate including a second alignment film; and
a negative liquid crystal layer including liquid crystal molecules and held between the array substrate and the counter-substrate, wherein
a direction of initial alignment of the liquid crystal molecules is substantially parallel to the first direction,
a photo-alignment treatment direction of the first alignment film or the second alignment film is substantially parallel to the first direction,
one of the gate lines extends parallel to the first direction,
the first pixel electrode and the second pixel electrode overlap the common electrode between the insulating substrate and the first alignment film in cross section,
the second pixel electrode is located adjacent to the first pixel electrode in the second direction,
the first pixel electrode has a first slit which is an opening of the first pixel electrode,
a long axis of the first slit extends in a first extension direction,
the second pixel electrode has a second slit which is an opening of the second pixel electrode,
a long axis of the second slit extends in a second extension direction different from the first extension direction,
the first extension direction crosses the second direction at a first acute angle in a clockwise direction, and is different from the first direction and the second direction, and
the second extension direction crosses the second direction at a second acute angle in a counterclockwise direction, and is different from the first direction and the second direction.
