摘要： A liquid crystal display includes an insulating substrate, an alignment layer covering a main surface of the insulating substrate, and electrodes interposed therebetween. The alignment layer defines an alignment direction parallel to the main surface, an upstream side as one end's side of the alignment direction, and a downstream side as another end's side of the alignment direction, and tilts liquid crystal molecules toward the downstream side. Each electrode includes an upstream section that includes a first edge facing the upstream side and a downstream section that includes a second edge facing the downstream side and is provided with a recess recessed relative to the second edge. The first recess forms on the downstream section a third edge extending in the alignment direction and a fourth edge connecting the third edge to the second edge and facing the upstream side.
