ABSTRACT:
A display device includes: a first panel having a pixel region including a pixel electrode therein; a second panel having a common electrode facing the first panel; a liquid crystal layer having vertically aligned liquid crystal molecules interposed between the first and second panels; a first alignment layer disposed on the pixel electrode; and a second alignment layer disposed on the common electrode. At least one of the pixel electrode and the common electrode has a micro slit pattern. At least one of the first and second alignment layers divides the pixel region into domains, is formed to have pretilt directions corresponding to a given domain, and pretilts the vertically aligned liquid crystal molecules in the given domain. A direction of summed horizontal components of a fringe field at an edge of the pixel region is substantially equal to a direction of summed horizontal components of a pretilt direction of the at least one of the first and second alignment layer.
