Abstract

A method of making an LCD device including a displaying unit having a plurality of pixel areas defined by a plurality of gate lines and data lines disposed in longitudinal and transverse directions, a thin film transistor (TFT) formed in each of the pixel areas to be connected to a pixel electrode formed in the pixel area, and a gate pad and a data pad formed on ends of the corresponding gate line and data line; and a dummy region formed on an outer portion of the displaying unit, and including a gate shorting bar and a data shorting bar which are connected to the gate pads and the data pads to apply test signal(s) to the TFTs, wherein the data shorting bar is a single shorting bar.

Claims (19)

1. A method of fabricating a liquid crystal display device, the method comprising the steps of:

providing a liquid crystal display panel, the liquid crystal display panel including a displaying unit and a dummy region, the display unit including,

a plurality of pixel areas defined by a plurality of gate lines and a plurality of data lines,

a thin film transistor formed in each of the pixel areas and to be connected to a pixel electrode formed in that pixel area, and

a plurality of gate pads and data pads formed on ends of the corresponding gate line and data line; and

the dummy region disposed in an outer portion of the displaying unit, and including a gate shorting bar and a data shorting bar which are connected to the gate pads and the data pads respectively, the data shorting bar being a single bar connected to the data pads and the gate shorting bar including a first gate shorting bar connected to only odd gate pads and a second gate shorting bar connected to only even gate pads,

applying a test signal to at least on of the gate shorting bar and the data shorting bar to test the thin film transistor; and

processing the liquid crystal display panel.

2. The method of claim 1 , wherein the first and second gate shorting Bars are made of Cr, and the data shorting bar is made of Mo/AINd.

3. A method of fabricating a liquid crystal display device, the method comprising the steps of:

providing first and second substrates;

forming at least one liquid crystal display panel in the substrates, the liquid crystal display panel including a displaying unit and a dummy region, the display unit including,

a plurality of pixel area defined by a plurality of gate lines and a plurality of data lines,

a thin film transistor formed in each of the pixel areas and to be connected to a pixel electrode formed in that pixel area, and

a plurality of gate pads and data pads formed on ends of the corresponding gate line and data line; and

the dummy region being disposed in an outer portion of the displaying unit, and including a gate shorting bar and a data shorting bar which are connected to the gate pads and the data pads respectively, the data shorting bar being a single bar connected to the data pads and the gate shorting bar including a first gate shorting bar connected to only odd gate pads and a second gate shorting bar connected to only even gate pads;

applying a test signal to at least one of the gate shorting bar and the data shorting bar to test the thin film transistor; and

processing the substrates to separate liquid crystal display panel from the substrates.

4. The method of claim 3 , wherein the first and second gate shorting bars are made of Cr, and the data shorting bar is made of Mo/AINd.
