Patent ID: 8780309

Claim:
A mother panel of a liquid crystal display (LCD) having a lower substrate with a pixel electrode, an upper substrate with a common electrode, and a liquid crystal layer between the lower and upper substrates, the mother panel comprising: an external pad area including a common voltage external pad and a pixel voltage external pad on the lower substrate, the common voltage external pad and pixel voltage external pad being configured to be applied with respective common and pixel voltages from the outside; a panel area including a plurality of panels and a dummy area between the panels; and an external shorting point in the dummy area of the panel area, the external shorting point being connected to the common electrode, and the common voltage external pad being directly connected to the external shorting point, wherein the external shorting point is electrically connected to multiple panels in the panel area of the mother panel via the common electrode of the upper substrate, the common voltage external pad being electrically connected to the multiple panels via the shorting point.
