Claim:
1. A display panel comprising: a display area configured to display an image, and a peripheral area adjacent to the display area, wherein the peripheral area comprises a pad area in which a plurality of output pads are disposed, and the output pads are arranged in a matrix formed having M row*N column, M and N are normal numbers, M is 3 or larger than 3, the M row extending in a first direction and the N column extending, in a second direction which is substantially perpendicular to the first direction, each of the output pads has a center of the output pad spaced apart from a center of an adjacent output pad in the first direction by a distance D in the first direction, and each of the output pads is spaced apart from an adjacent output pad by a gap, each of the output pads has a center of the output pad spaced apart from a center of an adjacent output pad in the second direction by a pitch P in the first direction; and an equation “P<D/(M−1)” is satisfied, each of the output pads extends in the second direction, and has a width in the first direction, and each of the output pads comprises a first side having a first length and a second side having a second length, the first side extending in the second direction, the second side is in parallel with the first side, and the second length is smaller than the first length, wherein further the display panel comprises: a base substrate; a first output pattern disposed on the base substrate; a first insulation layer disposed on the first base substrate on which the first output pattern is disposed; a second output pattern disposed on the first insulation layer; and a second insulation layer disposed on the first insulation layer on which the second output pattern is disposed, wherein the output pads are disposed on the second insulation layer, the output pads comprises a first output pad in a first row and a second output pad in a second row, the first output pad is electrically connected to the first output pattern through a first contact hole formed through the first and second insulation layer, and the second output pad is electrically connected to the second output pattern through a second contact hole formed through the second insulation layer.
