Abstract
A display panel includes a base substrate, pixels, signal lines, a power line, signal pads, power pads, and a conductive portion electrically connected to the power pads and extending from an area overlapping the power pads to an edge of the base substrate. An opening is defined in conductive portion by a removed portion thereof.
Claims22
A display panel comprising:
- a base substrate in which a first area, a second area, and a third area are sequentially defined in a first direction;
- pixels disposed on the first area;
- signal lines disposed on the base substrate and electrically connected to the pixels;
- a power line disposed on the base substrate, wherein the power line supplies a power to the pixels;
- signal pads disposed on the second area, arranged in a second direction crossing the first direction, and electrically connected to the signal lines;
- power pads disposed on the second area, arranged in the second direction, and electrically connected to the power line;
- and
- a conductive portion comprising a first sub-conductive portion disposed on the second area of the base substrate and overlapping the power pads and a second sub-conductive portion disposed on the third area of the base substrate and spaced apart from the first sub-conductive portion,
- wherein the first sub-conductive portion and the second sub-conductive portion are electrically connected to a plurality of the same power pads arranged contiguous to each other in the second direction and the power line, and
- wherein an opening is defined in the second sub-conductive portion by a removed portion thereof.
