Abstract:
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, in which an internal space is formed between the interior surface of the first substrate and the interior surface of the second substrate; 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 vertically formed on the interior surface of the first substrate; and a plurality of pixels defined by the gate line and the data lines in a matrix, in which each pixel comprises at least one TFT formed on the interior surface of the first substrate and near the intersection of the gate line and the data line, 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 an identical triangle-wave profile and are symmetrical to each other; and wherein, the triangle-wave profile is formed by connecting a plurality of right-angled and equilateral triangles.
