ABSTRACT:
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.
