  • Publication number: 20070236639
    Abstract: An exemplary liquid crystal panel (11) includes a first substrate (12), a second substrate (13) opposite to the first substrate, and a liquid crystal layer sandwiched between the first and second substrates. The second substrate includes a main portion and an extending portion (15). The extending portion has a capacitor (18) provided thereat. The capacitor includes an auxiliary conductive layer (180), two printed lines (182, 183) disposed in a same plane and being parallel to the auxiliary conductive layer, and an insulating layer (181) between the printed lines and the auxiliary conductive layer. The two printed lines both overlap with the auxiliary conductive layer. Unlike in conventional art, a total thickness of the auxiliary conductive layer, the insulating layer, and the printed lines is typically much less than a thickness of the first substrate. Thus, the liquid crystal panel has a smaller size.
