Claim 0:
1. A display apparatus comprising:
a first power line in a display area;
a second power line in the display area; and
a plurality of pixels in the display area,
wherein each of the plurality of pixels comprises a first transistor and a light-emitting device,
wherein the first transistor comprises a gate electrode, a semiconductor layer, a first electrode and a second electrode, the first electrode and the second electrode respectively electrically connected to a source area and a drain area of the semiconductor layer, and
wherein the light-emitting device comprises:
a pixel electrode connected to the one of the first electrode and the second electrode of the first transistor;
an opposite electrode facing the pixel electrode; and
an emissive layer between the pixel electrode and the opposite electrode, and
wherein the first power line is electrically connected to first transistors of the plurality of pixels,
wherein the opposite electrode faces pixel electrodes of the plurality of pixels,
wherein the second power line is electrically connected to the opposite electrode,
wherein the second power line electrically connected to the opposite electrode of the light-emitting device comprises a plurality of 2-1 power lines extending in a first direction and a plurality of 2-2 power lines extending in a second direction different from the first direction and electrically connected to the plurality of 2-1 power lines,
wherein the 2-1 power lines and the 2-2 power lines are disposed in different layers in the display area, and
wherein the first electrode and the second electrode of the first transistor and one of the 2-1 power lines and the 2-2 power lines are disposed in a same layer.
