Patent ID: 7053972

Claim:
A method of fabricating an array substrate device for a liquid crystal display device, comprising: forming a gate line and a gate pad on a substrate, the gate line disposed along a first direction and the gate pad is connected to a first end of the gate line; forming a gate insulating layer over the substrate to cover the gate line and the gate pad; forming a data line and a data pad over the gate insulating layer, the data line disposed along a second direction to cross the gate line to define a pixel region, and the data pad is connected to a first end of the data line; forming a thin film transistor at a crossing region of the gate and data lines; sequentially forming a first inorganic insulating layer and a first organic insulating layer over the substrate to cover the thin film transistor, the data line, and the data pad; patterning the first organic insulating layer to expose portions of the first inorganic insulating layer corresponding to the gate and data pads; forming a second inorganic insulating layer over the patterned first organic insulating layer and over the exposed portions of the first organic insulating layer; simultaneously patterning the second inorganic insulating layer, the first organic insulating layer, and the first inorganic insulating layer to form first, second, and third contact holes; and forming a transparent pixel electrode, and a transparent gate pad terminal, and a data pad terminal over the second inorganic insulating layer, wherein the pixel electrode contacts a portion of the thin film transistor through the first contact hole, and the gate pad terminal and data pad terminal contact the gate and data pads through the second and third contact holes, respectively.
