Abstract:
1. A data line structure in a lead region of a thin film transistor liquid crystal display (TFT-LCD) comprising: a substrate; a gate layer data line segment in the lead region on the substrate; a dielectric layer on the gate layer data line segment in the lead region; a data line lead on the dielectric layer in the lead region, wherein the gate layer dataline segment extends corresponding to the data line lead; a passivation layer on the data line lead in the lead region; a via hole formed in the data line lead; a connection hole formed in a portion of the dielectric layer and a portion of the passivation layer in a position corresponding to the via hole and together with the via hole; and a connection line segment provided in the connection hole, wherein the gate layer data line segment and the data line lead are connected by the connection line segment in the connection hole.
