Abstract
A pixel electrode structure for a liquid crystal display with a high aperture ratio increases the aperture ratio and eliminates Mura phenomenon. Any two adjacent pixel electrodes are disconnected to each other. 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. The first-lengthwise periphery and the second-lengthwise periphery have an identical triangle-wave profile and are symmetrical to each other. The triangle-wave profile is formed by connecting a plurality of right-angled and equilateral triangles.

A liquid crystal display, comprising:
- a first substrate and a second substrate disposed opposite each other with a liquid crystal layer interposed therebetween;
- a plurality of pixels defined by crossing gate and data lines formed on the first substrate;
- and
- a pixel electrode having a first wave-shaped edge portion formed over the first substrate in each pixel, wherein the pixel electrode overlaps a portion of the data line to form an overlapping portion;
- wherein the area of the overlapping portion is equal to or larger than the area of the first wave-shaped edge portion.
A liquid crystal display, comprising:
- crossing gate and data lines formed on a substrate;
- and
- a plurality of pixel electrodes formed in an area defined by the gate and data lines, wherein two adjacent pixel electrodes are disconnected to each other;
- wherein each pixel electrode comprises a first wave-shaped edge portion overlapped with a portion of the data line;
- wherein the data line has a second wave-shaped edge portion;
- wherein the second wave-shaped edge portion corresponds to the first wave-shaped edge portion.
