Display device

A display device comprising:

• a substrate;
• a first pixel, a second pixel, a third pixel, and a fourth pixel arranged in a first direction on the substrate;
• a first data signal line connected to the first pixel;
• a second data signal line connected to the second pixel;
• a third data signal line connected to the third pixel;
• and
• a fourth data signal line connected to the fourth pixel,
• wherein the first to fourth data signal lines extend in the first direction,
• the first data signal line includes a first upper conductive layer and a first lower conductive layer connected to the first upper conductive layer via a first contact hole, the first lower conductive layer being located between the substrate and the first upper conductive layer,
• the second data signal line includes a second upper conductive layer and a second lower conductive layer connected to the second upper conductive layer via a second contact hole, the second lower conductive layer being located between the substrate and the second upper conductive layer,
• the third data signal line includes a third upper conductive layer and a third lower conductive layer connected to the third upper conductive layer via a third contact hole, the third lower conductive layer being located between the substrate and the third upper conductive layer,
• the fourth data signal line includes a fourth upper conductive layer and a fourth lower conductive layer connected to the fourth upper conductive layer via a fourth contact hole, the fourth lower conductive layer being located between the substrate and the fourth upper conductive layer,
• the first lower conductive layer intersects the third upper conductive layer in a plan view, and
• the second upper conductive layer intersects the fourth lower conductive layer in a plan view.
