Patent ID: 7554640

Claim:
A liquid crystal display device comprising: a least one red pixel including a red color filter and a pixel electrode; at least one green pixel including a green color filter and a pixel electrode; at least one blue pixel including a blue color filter and a pixel electrode; and at least one white pixel including a white color filter and a pixel electrode; wherein a first row of pixels includes a first red pixel, a first green pixel, a first blue pixel, and a first white pixel, and a second row of pixels includes a second red pixel, a second green pixel, a second blue pixel and a second white pixel; wherein each pixel electrode includes one part extending in one direction along a signal line and a plurality of other parts connected to and extending from the one part, and substantially all of the plurality of other parts of a respective pixel electrode extend from the one part in one of a first direction and a second direction which is different from the one direction; wherein substantially all of the plurality of other parts of the pixel electrode of the first red pixel, the first green pixel, and the first blue pixel of the first row of pixels extend along the first direction; wherein substantially all of the plurality of other parts of the pixel electrode of the second red pixel, the second green pixel, and second blue pixel of the second row of pixels extend along the second direction; and wherein substantially all of the plurality of other parts of the pixel electrode of the first white pixel of the first row of pixels extend along the second direction, and substantially all of the plurality of other parts of the pixel electrode of the second white pixel of the second row of pixels extend along the first direction.
