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.

Pixel electrode structure for a liquid crystal display with a high aperture ratio

A method of repairing an LCD panel having a mura defect is disclosed. The closed seal pattern of the LCD panel has a shape of frame with at least one jut portion directing to a peripheral side of the two substrates. Thus, when a mura defect occurs, a peripheral portion on one side of the two substrates is cut off, wherein the cutting passes across the jut portion of the closed seal pattern to form an opening with respect to the sealed region. An extra amount of liquid crystal can be pressed out through the opening. Then the opening is sealed using a sealant, such that the LCD panel having a mura defect is repaired.
