Patent ID: 7110077

Claim:
A pixel electrode structure for a liquid crystal display with a high aperture ratio, comprising: a first substrate and a second substrate disposed parallel to each other with an internal space interposed therebetween; a liquid crystal layer formed in the internal space; at least one polarizer formed on the exterior surface of the first substrate or the exterior surface of the second substrate; a plurality of parallel gate lines transversely formed on the interior surface of the first substrate; a plurality of parallel data lines longitudinally formed on the interior surface of the first substrate; and a plurality of pixels defined by the gate line and the data lines and in a matrix, in which each pixel comprises a common electrode formed on the interior surface of the second substrate and covering the pixel, and a pixel electrode formed on the interior surface of the first substrate and covering the pixel; wherein two adjacent pixel electrodes are disconnected to each other; wherein each pixel electrode comprises a first-lengthwise periphery that overlaps a first-adjacent data line to form a first overlapping portion, and a second-lengthwise periphery that overlaps a second-adjacent data line to form a second overlapping portion; wherein the first-lengthwise periphery and the second-lengthwise periphery have a square-wave profile, and the square-wave profile is formed by connecting a square protrusion and a square indentation in sequence; wherein the area of the first overlapping portion is equal to or larger than the total area of the square protrusions of the first-lengthwise periphery.
