Liquid crystal display

A liquid crystal display comprising:

• a liquid crystal layer exhibiting Kerr effect;
• a first electrode including combtooth portions facing one main surface of the liquid crystal layer, the combtooth portions each extending in a first direction and arranged in a second direction, the first and second directions being parallel with the main surface and crossing each other, each of the combtooth portions including
• a pair of first portions each extending in the first direction and arranged in the second direction, each of the first portions having a surface parallel with the first and second directions, and
• a second portion extending in the first direction between the first portions and having a surface including a first convex surface, the first convex surface having a ridge shape and extending in the first direction;
• and
• a second electrode electrically insulated from the first electrode, the second electrode including a portion that faces the main surface and is positioned in a gap between the combtooth portions or faces the main surface with the gap interposed therebetween.

• a first electrode including combtooth portions facing one main surface of the liquid crystal layer, the combtooth portions each extending in a first direction and arranged in a second direction, the first and second directions being parallel with the main surface and crossing each other;
• an insulating layer facing the main surface with the first electrode interposed therebetween;
• and
• a second electrode electrically insulated from the first electrode, the second electrode including a portion that faces the main surface with the insulating layer interposed therebetween and another portion protruding toward the liquid crystal layer at a position corresponding to a gap between the combtooth portions.
