Display device

A display device, comprising:

• pixels each comprising a light emitting element;
• pixel defining layer having openings which define light emitting areas of the pixels;
• data lines and a dummy data line extending parallel to each other, the data lines being connected to the pixels;
• and
• power lines and a dummy power line extending parallel to each other, the power lines being connected to the pixels,
• wherein the light emitting element comprises a first electrode, an emitting layer, and a second electrode that are located in a corresponding light emitting area from among the light emitting areas,
• wherein, in a plan view, each of the data lines and the power line overlaps at least one of the openings of the pixel defining layer, and
• wherein, in a plan view, the dummy data line and the dummy power line do not overlap the openings of the pixel defining layer.

A display device, comprising:

• pixels each comprising a transistor and a light emitting element connected to the transistor, the transistor comprising an active pattern;
• data lines connected to the transistor of each of the pixels;
• power lines connected to the transistor of each of the pixels;
• a dummy data line extending parallel to the data lines;
• a dummy power line extending parallel to the power lines;
• and
• a dummy active pattern connected to the dummy data line and the dummy power line.
