Pixel structure

A pixel structure, comprising:

• a pixel electrode, wherein an outline of the pixel electrode is surrounded by a first long side, a first short side, a second long side, and a second short side, and the pixel electrode has a first opening and a second opening, wherein the first long side is opposite to the second long side, the first short side is opposite to the second short side, the first opening substantially extends along the first long side, the second opening extends from the first opening toward the second long side, and a width of the first opening is smaller than a width of the second opening;
• and
• an alignment electrode, physically separated from the pixel electrode, and comprising a first extension portion adjacent to the second long side and two supplemental portions positioned at two ends of the first extension portion, wherein the two supplemental portions extend from the first extension portion toward the first long side and respectively along the first short side and the second short side,
• wherein the first extension portion has an extension portion opening located inside the first extension portion, a width of the extension portion opening increases toward a middle, and an extension line of the second opening traverses a wide portion of the extension portion opening.

• wherein a distance between the first long side and the second long side shows a variation tendency of first increasing and then decreasing along an extension direction of the first long side.
