Abstract:
1. A common line structure, disposed on a substrate, the common line structure comprising: at least one first common section, disposed on the substrate; at least one second common section, disposed on the substrate, wherein the first common section and the second section are made of a same patterned conducting layer; a passivation layer, disposed on the at least one first common section and on the at least one second common section, wherein the passivation layer having at least one through hole, partially exposing the at least one first common section and the at least one second common section, the at least one through hole comprises a first through hole and a second through hole, the first through hole partially exposes the first common section, and the second through hole partially exposes the second common section; a connection section, disposed on the passivation layer, wherein the connection section is electrically connected to the at least one first common section and to the at least one second common section exposed by the through hole; and an insulated layer, disposed between the first common section and the passivation layer, and between the first common section and the second common section, wherein the first through hole penetrates the passivation layer and the insulated layer to partially expose the first common section, and the second through hole penetrates the passivation layer and the insulated layer to partially expose the second common section, wherein a sidewall of the insulated layer exposed by the first through hole and a sidewall of the insulated layer exposed by the second through hole respectively have a stair structure, and each of the stair structures comprises a first slanted surface, a flat surface, and a second slanted surface.
