1. A display device, comprising:
a substrate including a display area and a non-display area;
a buffer layer on the substrate;
a semiconductor layer on the buffer layer;
a first insulating layer on the semiconductor layer;
a first gate layer on the first insulating layer;
a second insulating layer on the first gate layer;
a second gate layer on the second insulating layer;
a third insulating layer on the second gate layer;
a source electrode on the third insulating layer;
a fourth insulating layer on the source electrode;
a first signal line in the display area of the substrate and extended in a first direction, the first signal line is disposed on the fourth insulating layer;
a first dummy pattern from among a plurality of first dummy patterns in the display area and extended in the first direction, a first dummy pattern is disposed on the fourth insulating layer;
a fifth insulating layer on the first signal line and the first dummy pattern;
a second signal line on the fifth insulating layer and extended in a second direction;
a second dummy pattern on the fifth insulating layer and extended in the second direction;
a sixth insulation layer on the second signal line and the second dummy pattern;
an anode on the sixth insulating layer;
an organic light emitting layer on the anode;
a cathode on the organic light emitting layer; and
a third signal line in the non-display area,
wherein the first signal line and the first dummy pattern are in a same layer,
wherein the first dummy pattern is adjacent to the first signal line,
wherein a first gap is between one end or an other end of the first signal line and one end or an other end of the first dummy pattern,
wherein the second signal line and the second dummy pattern are in a same layer,
wherein the second dummy pattern is adjacent to the second signal line,
wherein a second gap is between one end or an other end of the second signal line and one end or an other end of the second dummy pattern, and
wherein the first dummy pattern is electrically connected to the third signal line in the non-display area.
