Patent ID: 8810763

Claim:
A pixel electrode structure of a display device, for being disposed in an upper left sub pixel region, an upper right sub pixel region, a lower left sub pixel region and a lower right sub pixel region of a pixel region, the pixel electrode structure comprising: a plurality of first sub pixel electrodes on the upper left sub pixel region and the upper right sub pixel region, and each having at least two ends opposite to each other; and a plurality of second sub pixel electrodes on the lower left sub pixel region and the lower right sub pixel region, and each having at least two ends opposite to each other, wherein one first sub pixel electrode includes a first portion on the upper left sub pixel region and a second portion on the upper right sub pixel region, wherein one second sub pixel electrode includes a first portion on the lower left sub pixel region and a second portion on the lower right sub pixel region, wherein the first portion of the one first sub pixel electrode is symmetrical to the second portion of the one first sub pixel electrode with respect to a vertical line and is symmetrical to the first portion of the one second sub pixel electrode with respect to a horizontal line perpendicular to the vertical line, wherein the second portion of the one second sub pixel electrode is symmetrical to the first portion of the one second sub pixel electrode with respect to the vertical line and is symmetrical to the second portion of the one first sub pixel electrode with respect to the horizontal line, wherein the upper right sub pixel region and the upper left sub pixel region form a first pixel region and the lower right sub pixel region and the lower left sub pixel region form a second pixel region, wherein each of the plurality of first sub pixel electrodes has a bent line shape and is disposed substantially in parallel to each other, wherein the plurality of first sub pixel electrodes have progressively greater widths and progressively greater intervals therebetween starting from one side of the first pixel region near the horizontal line between the first and second pixel regions to the other side of the first pixel region opposite to the one side of the first pixel region, wherein the upper right sub pixel region and the upper left sub pixel region form a first pixel region and the lower right sub pixel region and the lower left sub pixel region form a second pixel region, wherein each of the plurality of second sub pixel electrodes has a bent line shape and is disposed substantially in parallel to each other, and wherein the plurality of second sub pixel electrodes have progressively greater widths thereof and progressively greater intervals therebetween starting from one side of the second pixel region near the horizontal line to the other side of the second pixel region opposite to the one side of the second pixel region.
