Claim:
1. A display device, comprising: a first substrate that has a first electrode and a second electrode, a second substrate that faces the first substrate; and a liquid crystal layer disposed between the first substrate and the second substrate, wherein when a voltage is not applied to the first electrode and the second electrode, the major axes of the liquid crystal molecules are oriented so as to be aligned in a third direction parallel to the second direction, whereas when a voltage is applied between the first electrode and the second electrode, the major axes of the liquid crystal molecules are oriented so as to rise in a direction perpendicular to the first substrate while rotating in an in-plane direction of the first substrate, clockwise in a vicinity of one of long sides of the comb tooth portions that face each other in a width direction of the slits and counterclockwise in a vicinity of the other of the long sides, each comb tooth portion has a shape substantially symmetric with respect to a predetermined axis, the predetermined axis being parallel to the second direction and the third direction serving as an initial orientation direction of the liquid crystal molecules, each comb tooth portion has a first long side and a second long side facing each other, the first long side of each comb tooth portion has at least a first line segment and a second line segment, the first line segment is arranged on a distal end side of each comb tooth portion and has a first angle with respect to the third direction, and the second line segment is arranged on a base side of each comb tooth portion and has a second angle with respect to the third direction, the second long side of each comb tooth portion has at least a third line segment and a fourth line segment, the third line segment is arranged on the distal end side of each comb tooth portion and has a third angle with respect to the third direction, and the fourth line segment is arranged on the base side of each comb tooth portion and has a fourth angle with respect to the third direction, the second angle is larger than the first angle, the fourth angle is larger than the third angle, the first angle is substantially equal to the third angle, and the second angle is substantially equal to the fourth angle.
