Patent ID: 7701526

Claim:
A liquid crystal display device, comprising: a first substrate including a first display area having a first side, a second side adjacent to the first side and third and fourth sides, and a first non-display area at the first and second sides of the first display area; a second substrate facing the first substrate and including a second display area corresponding to the first display area and having the first to the fourth sides, and a second non-display area at one of the third and the fourth sides of the second display area, wherein at least a portion of the second non-display area is not overlapped with the first substrate; a thin film transistor over an inner surface of the first substrate; a pixel electrode connected to the thin film transistor; a common line in the first non-display area; a common electrode over an inner surface of the second substrate and a silver (Ag) dot connecting the common line and the common electrode, wherein a common voltage is applied to the common electrode through the silver (Ag) dot, wherein the common electrode is substantially disposed in the second display area and at least the portion of the second non-display area that is not overlapped with the first substrate, and wherein the portion of the second non-display area is provided for applying a voltmeter for measuring the common voltage applied to the common electrode through the common line and the silver (Ag) dot, whereby the common voltage of the common electrode in the second non-display area can be measured to confirm whether the silver (Ag) dot is defective; and a liquid crystal layer between the pixel electrode and the common electrode.
