Abstract
A pixel structure includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. Each of first pixel electrodes has first branch portions. Each of the first pixel electrodes has a first outline. The first branch portions of each of the first pixel electrodes and one of first connecting electrodes have a first junction. The first junction has a length. The first outline has a length. Each of the first sub-pixel, the second sub-pixel, and the third sub-pixel has a first ratio of the length of the first junction to the length of the first outline. The first ratios of at least two of the first sub-pixel, the second sub-pixel, and the third sub-pixel are substantially different.
