4. The thin film panel of claim 3 , wherein the first signal line and the second signal line each comprise a first layer and a second layer, and wherein the first layers of each of the first and second signal lines comprises chromium or a chromium alloy.
5. The thin film panel of claim 4 , wherein the second layer of each of the first and second signal lines comprises aluminum or an aluminum alloy.
6. The thin film panel of claim 1 , further comprising:
a shorting bar connected to the second signal line.
7. The thin film panel of claim 1 , further comprising:
a gate line to transmit gate signals; and
a data line to transmit data signals,
wherein the gate line is formed in the same layer as the first signal line and the data line is formed in the same layer as the second signal line.
8. The thin film panel of claim 1 , wherein the divided portion of the second signal line is electrically connected to the first signal line through the connector assistant.
9. The thin film panel of claim 1 , wherein the first insulating layer is exposed through the divided portion.
10. The thin film panel of claim 6 , further comprising:
a gate line to transmit sate signals; and
a data line to transmit data signals,
wherein the gate line is formed in the same layer as the first signal line and the data line is formed in the same layer as the second signal line.
11. A thin film panel comprising:
a first signal line;
a second signal line crossing the first signal line and formed on a different layer from the first signal line, wherein the second signal line includes an expansion, the expansion has an enlarged area and at least one cutout, and the expansion is disposed adjacent to a crossing region where the second signal line crosses the first signal line;
a first insulating layer formed between the first signal line and the second signal line; and
a second insulating layer formed on the second signal line, wherein the second insulating layer has at least one first contact hole exposing a portion of the expansion of the second signal line; and
a connector assistant formed adjacent to the crossing region,
wherein the second signal line is electrically connected to the first signal line using the connector assistant, and wherein the first and second insulating layers have a second contact hole exposing a portion of the first signal line and the connector assistant electrically connects the first signal line to the second signal line through the first and second contact holes.
12. The thin film panel of claim 11 , wherein the second signal line comprises a first layer and a second layer, and wherein the portion of the expansion of the second signal line exposed through the first contact hole comprises the first layer of the second signal line.
13. The thin film panel of claim 12 , wherein the first insulating layer is exposed through the at least one cutout of the expansion.
14. The thin film panel of claim 13 , wherein the first signal line and the second signal line each comprise a first layer and a second layer, and wherein the first layers of each of the first and second signal lines comprises chromium or a chromium alloy.
15. The thin film panel of claim 14 , wherein the second layer of each of the first and second signal lines comprises aluminum or an aluminum alloy.
16. The thin film panel of claim 11 , wherein the first insulating layer is exposed through the at least one cutout of the expansion.
