LIQUID CRYSTAL DISPLAY
First Claim
1. A liquid crystal display comprising:
- a liquid crystal layer driven by a vertical alignment mode; and
pixel electrodes,each two pixel electrodes being disposed adjacent to each other in a first direction so as to sandwich a slit therebetween, the two pixel electrodes separately accepting writing-in of data signals, the first direction being a direction in which data signal lines extend, and the liquid crystal layer, corresponding to at least one of the two pixel electrodes, having an alignment control structure disposed on its counter electrode,one pixel electrode of the two pixel electrodes having a first edge being an edge serving as a borderline between the one pixel electrode and the slit, and the other pixel electrode of the two pixel electrodes having a second edge being an edge serving as a borderline between the other pixel electrode and the slit, the first edge and the second edge being not uniformly parallel to each other along a direction that is perpendicular to the first direction,the first edge and the second edge sharing a bisector that extends along the first direction and runs through centers of the first edge and the second edge,one or both of the first edge and the second edge having a protrusion provided extending into the slit in the first direction, the protrusion(s) being increased just along a direction from a region on one predetermined side of the bisector to another region on the other side of the bisector, the region on one predetermined side of the bisector and the another region on the other side of the bisector being regions on the first and second edges on which the protrusion(s) are provided, 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.

Abstract
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.
