Display device and method for manufacturing display device

A display device, comprising:

• a substrate;
• signal lines disposed on the substrate, the signal lines including a gate line, a data line, and a driving voltage line;
• a transistor connected to at least one of the signal lines and comprising a semiconductor layer, a first electrode overlapping the semiconductor layer, and a second electrode and a third electrode connected to the semiconductor layer through a first contact hole and a second contact hole;
• a first electrode disposed on portions of the signal lines and the transistor and connected to the transistor;
• a pixel defining layer disposed on a portion of the first electrode and overlapping the signal lines and the transistor;
• an organic emission layer disposed in regions surrounded by the pixel defining layer;
• a second electrode disposed on the pixel defining layer and the organic emission layer;
• and
• a first capacitor and a second capacitor disposed on the substrate,
• wherein one of the first capacitor and the second capacitor includes a first capacitor electrode formed with a same layer as the semiconductor layer of the transistor and the other one of the first capacitor and the second capacitor includes a second capacitor electrode formed with a same layer as the second electrode or the third electrode of the transistor.
