Display device

A display device comprising:

• a plurality of pixels;
• a substrate comprising an active area in which the plurality of pixels is disposed and a non-active area disposed on a side of the active area;
• a first data conductive layer disposed on the substrate and comprising a plurality of signal wires connected to the plurality of pixels;
• a first insulating layer disposed on the first data conductive layer;
• a second data conductive layer disposed on the first insulating layer and comprising a connection wire connected to some of the plurality of signal wires and a plurality of dummy wiring patterns that is disconnected from the plurality of signal wires;
• a second insulating layer disposed on the second data conductive layer;
• and
• a pixel electrode disposed on the second insulating layer,
• wherein the plurality of dummy wiring patterns is separated from one another at a disconnection,
• wherein the second insulating layer comprises a first portion disposed on the dummy wiring patterns, a second portion disposed on the disconnection, and a third portion disposed on at least a portion of the connection wire, and
• wherein a second thickness of the second portion is different from a third thickness of the third portion.
