Abstract:
1. A method of forming an array substrate device for use in a liquid crystal display device, comprising: forming a gate line on a substrate along a first direction, the gate line including a gate pad at one end thereof; forming a first insulating layer on the substrate to cover the gate line; forming a data line over the first insulating layer along a second direction perpendicular to the first direction on the substrate, the data line defining a pixel region with the gate line and including a data pad at one end thereof; forming a thin film transistor at a crossing region of the gate and data lines, the thin film transistor including a gate electrode, a semiconductor layer, a source electrode, and a drain electrode; forming a black matrix overlapping the thin film transistor, the gate line, and the data line except a first portion of the drain electrode; forming a second insulating layer over an entire surface of the substrate to cover the black matrix; patterning the first and second insulating layers to expose the first portion of drain electrode, to form a gate pad contact hole exposing the gate pad, and to form a data pad contact hole exposing the data pad; forming a first transparent electrode layer over an entire surface of the substrate to cover the patterned second insulating layer and contacting the exposed first portion of the drain electrode; dropping a liquid-type color resin onto the first transparent electrode layer within the pixel region to form a color filter within the pixel region; forming a second transparent electrode layer over an entire surface of the substrate to cover the color filter and the first transparent electrode layer; and patterning the first and second transparent electrode layers to form first and second pixel electrodes, a double-layered gate pad terminal, and a double-layered data pad terminal.
