Active-matrix display device

An active-matrix display device comprising:

• a plurality of pixels arranged in a matrix, each of the plurality of pixels including:
• a drive element that is disposed on a substrate;
• and
• a light-emitting element that is caused by the drive element to emit light, and includes a metal electrode layer disposed above the substrate and a transparent electrode layer disposed above the metal electrode layer;
• a data line that is disposed on the substrate and supplies data to the plurality of pixels;
• and
• a power supply line that is disposed on the substrate and supplies electric power to the plurality of pixels,
• wherein
• the power supply line is shared by, among the plurality of pixels, two pixels that are adjacent to each other in a second direction that crosses a first direction in which the power supply line is extended,
• the data line and the metal electrode layer are disposed not to overlap each other in a plan view of the substrate,
• each of the plurality of pixels further includes a capacitor that is disposed on the substrate and that holds a voltage corresponding to the data,
• the power supply line includes:
• a first power supply line that supplies a current to the light-emitting element;
• and
• a second power supply line that supplies a voltage that initializes a voltage of the capacitor, and
• the first power supply line and the second power supply line are disposed alternately every other pixel along the second direction.
