1. A liquid crystal display device, comprising:
at least one scanning signal line extending in a first direction;
at least one data signal line intersecting the at least one scanning signal line; and
a pixel including a pixel electrode, a common electrode opposite the pixel electrode, and a liquid crystal layer,
wherein:
the common electrode includes a slit arranged in a region overlapping the pixel electrode;
the slit includes a slit center portion that has a middle part of the slit in a second direction orthogonal to the first direction;
the slit center portion has a side that is a portion of a periphery of the slit and is a straight line extending a third direction that is different from the first direction and the second direction;
the first direction and the third direction make a first angle;
the at least one data signal line includes a portion that is adjacent to the slit center portion, faces the middle part, and extends at a second angle with respect to the first direction;
the first angle and the second angle are acute angles,
the first angle is one of a positive angle and a negative angle with respect to the first direction,
the second angle is the one of the positive angle and the negative angle with respect to the first direction, and
the first angle and the second angle are different in a range of 1 degree to 5 degrees.
