Abstract
Each of branch portions of a pixel electrode and inclined portions of data lines extends in a direction different from an x direction and a y direction in a pixel region and inclined with respect to the y direction. Further, a liquid crystal layer is orientated in a direction different from the x direction and the y direction in the pixel region and inclined with respect to the y direction.
Claims9
A liquid crystal display apparatus comprising:
- a liquid crystal panel having a pixel region in which a plurality of pixels are provided in a matrix in a first direction and a second direction perpendicular to the first direction;
- a pixel electrode and a common electrode that apply a transverse electric field to a liquid crystal layer such that an image is displayed in said pixel region with light emitted through said liquid crystal layer;
- a plurality of first wire lines disposed in a spaced relationship from each other in the second direction with regard to the plurality of pixels so as to define a plurality of pixels juxtaposed in the second direction;
- a plurality of second wire lines disposed in a spaced relationship from each other in the first direction with regard to the plurality of pixels so as to define a plurality of pixels juxtaposed in the first direction;
- and
- a color filter layer comprising a red filter layer a green filter layer and a blue filter layer juxtaposed with each other in the first direction,
- wherein,
- (a) each of said second wire lines includes an inclined portion extending in a direction different from the first and second directions in said pixel region and inclined with respect to the second direction,
- (b) said pixel electrode includes (1) two trunk portions extending in the first direction, (2) a plurality of branch portions extending in a third direction in said pixel region, each of the plurality of branch portions inclined in a same direction, and (3) each end of the plurality of branch portions connected to a respective trunk portion,
- (c) each of said inclined portion and said branch portions is inclined in the same direction with respect to the second direction,
- (d) the common electrode is formed over an entire display region including all of the pixel regions,
- (e) an overall shape of each of the red filter layer, the green filter layer, and the blue filter layer extends in a direction inclined with respect to the second direction and is aligned with the branch portions, and
- (f) the inclined portion of the second wire is formed on the side opposite to the pixel electrode with respect to the common electrode in a direction of thickness of the liquid crystal panel.
