Liquid crystal display device
An LCD device includes a plurality of data pads; an LCD panel defined by a plurality of pad regions; a first shorting bar connected to odd numbered data pads among the plurality of data pads; a second shorting bar connected to even numbered data pads among the plurality of data pads; and a test pad formed in a predetermined portion of a pad region among the plurality of pad regions to apply a signal voltage for on/off testing to the first shorting bar and the second shorting bar.
1. An LCD device comprising:
a plurality of data pads;
an LCD panel defined by a plurality of pad regions;
a first shorting bar connected to odd numbered data pads among the plurality of data pads;
a second shorting bar connected to even numbered data pads among the plurality of data pads; and
a test pad formed in a predetermined portion of a pad region among the plurality of pad regions to apply a signal voltage for on/off testing to the first shorting bar and the second shorting bar.
2. The LCD device as claimed in claim 1 , wherein the test pad includes:
a first conductive pattern connected to the first shorting bar;
a second conductive pattern connected to the second shorting bar; and
a transparent conductive film electrically connecting the first conductive pattern to the second conductive pattern.
3. The LCD device as claimed in claim 2 , wherein the first and second conductive patterns are disposed with a gate insulating film interposed therebetween.
4. The LCD device as claimed in claim 3 , wherein the first conductive pattern is formed on a substrate, and the second conductive pattern is formed on the gate insulating film.
5. The LCD device as claimed in claim 2 , further comprising a passivation film formed on an entire surface of a substrate including the second conductive pattern, the passivation film including a contact hole that exposes predetermined portions of the first conductive pattern and the second conductive pattern.
6. The LCD device as claimed in claim 1 , wherein the first shorting bar and the second shorting bar are disposed with a gate insulating film interposed therebetween.
7. The LCD device as claimed in claim 6 , wherein the first shorting bar is formed on a same layer as a first conductive pattern, and the second shorting bar is formed on a same layer as a second conductive pattern.
8. The LCD device as claimed in claim 1 , further comprising:
a plurality of gate pads;
a third shorting bar connected to odd numbered gate pads among the plurality of gate pads; and
a fourth shorting bar connected to even numbered gate pads among the plurality of gate pads.
9. The LCD device as claimed in claim 8 , wherein a test pad applying a signal voltage to the third shorting bar is formed in a different portion than a test pad applying a signal voltage to the fourth shorting bar.
