A first edge (61a) and a second edge (61b) are not uniformly parallel to each other in a direction perpendicular to a first direction (A); a protrusion that is provided on one or both of the first edge (61a) and the second edge (61b), which protrusion protrudes into a slit (62b), is increased in just a direction from one predetermined region on one side of a bisector (C) shared by the first edge (61a) and the second edge (61b) to another region on the other side of the bisector C, which region on one predetermined region and the another region on the other side are regions of the first edge (61a) and the second edge (61b), and all of the protrusion(s) being extended into the slit to reach its maximum in the another region on the other side of the bisector. As a result, it is possible to achieve a liquid crystal display that is capable of generating alignment centers of liquid crystal molecules so that alignment centers of pairs of adjacent pixel electrodes are generated in uniform, which alignment center is generated in the vicinity of a slit sandwiched between pixel electrodes that are provided adjacent to each other in a direction in which the data signal lines extend and that are applied a voltage separately.
