Organic electroluminescent display device including a dummy pattern for preventing short circuiting
An organic electroluminescent display device may have a dummy pattern that can induce a charge difference between interconnection lines and thus prevent a short circuit between the interconnection lines resulting from the charge difference. The organic electroluminescent display device may include a substrate and a plurality of metal lines arranged in a vertical direction and in a transverse direction on the substrate, as well as a dummy pattern formed between adjacent metal lines.
1. An organic electroluminescent display device, comprising:
a plurality of metal lines arranged in a vertical direction and in a transverse direction on a substrate; the plurality of metal lines comprising:
a first metal line in a first direction;
a second metal line comprising an end portion connected to the first metal line;
a third metal line arranged in parallel with the second metal line and passing the first metal line; and
a dummy pattern formed between the second metal line and the third metal line.
2. The device of claim 1 ,
wherein the dummy pattern is formed in the first metal line to be closer to the second metal line than the third metal line.
3. The device of claim 2 , wherein the dummy pattern is formed at a location adjacent to one side of the end portion of the second metal line that is connected to the first metal line.
4. The device of claim 2 , wherein the dummy pattern is formed at a location adjacent to the other side of the end portion of the second metal line that is not connected to the first metal line.
5. An organic electroluminescent display device comprising:
a substrate; and
a plurality of metal lines arranged in a vertical direction and in a transverse direction on the substrate, the plurality of metal lines comprising:
a first metal line arranged in one direction;
a second metal line arranged in parallel with the first metal line;
a third metal line having an end portion connected to the first metal line and being arranged in a perpendicular direction thereto; and
a fourth metal line having an end portion connected to the second metal line and being arranged in parallel with the third metal line and passing the first metal line,
wherein dummy patterns are formed in the first and second metal lines, respectively.
6. The device of claim 5 , wherein the dummy pattern is formed in the first metal line to be closer to the third metal line than the fourth metal line.
7. The device of claim 6 , wherein the dummy pattern is formed at a location adjacent to one side of the end portion of the third metal line that is connected to the first metal line.
8. The device of claim 6 , wherein the dummy pattern is formed at a location adjacent to the other side of the end portion of the third metal line that is connected to the first metal line.
9. The device of claim 5 , wherein the dummy pattern is formed at a location adjacent to the end portion of the fourth metal line that is connected to the second metal line.
10. An organic electroluminescent display comprising:
a substrate; and
a plurality of metal lines arranged in a vertical direction and in a transverse direction on the substrate, the plurality of metal lines comprising:
a plurality of source and drain metal lines arranged in parallel in one direction;
a plurality of gate metal lines comprising an end portion connected to the plurality of source and drain metal lines; and
a dummy pattern arranged in at least one of the source and drain metal lines that connect to the gate metal lines.
11. The device of claim 10 , wherein the dummy pattern is formed in at least one of the source and drain metal lines at a location adjacent to a periphery of the gate metal line pattern that accumulates a charge.
