Abstract
In a liquid crystal display, a pretilt value provided by an upper alignment layer or a lower alignment layer is gradually changed in one domain, such that liquid crystal molecules have various arrangements in which azimuth angles of aligned liquid crystal molecules are gradually changed.
Claims15
A liquid crystal display, comprising:
- a plurality of pixel regions each including a plurality of domains;
- a lower panel including a lower substrate, and a lower alignment layer on the lower substrate and including a pretilt;
- an upper panel including an upper substrate and an upper alignment layer disposed on the upper substrate and including a pretilt;
- and
- a vertical alignment mode liquid crystal layer between the lower panel and the upper panel, and having a plurality of liquid crystal molecules,
- wherein
- liquid crystal molecules which are adjacent to the upper alignment layer or the lower alignment layer are arranged by a respective pretilt, and
- the pretilt of the lower alignment layer or the upper alignment layer is gradually changed along a first direction from a side to an opposite side in each of the plurality of domains of the plurality of pixel regions in a plan view, and is the same in each of the plurality of domains of the plurality of pixel regions along a second direction perpendicular to the first direction in the plan view.
