Abstract: A display device according to an embodiment of the present disclosure may include pixels including a first pixel and a second pixel sequentially arranged in a display area along a first direction, each of the first pixel and the second pixel including sub pixels arranged along a second direction corresponding to emission areas, and a first power line and a second power line connected to the pixels. Each of the sub pixels may include a light emitting element, a first electrode connected between the light emitting element and the first power line, and a second electrode connected between the light emitting element and the second power line. The second electrodes of the sub pixels of the first and second pixels may be integrally connected to each other to configure an integrated electrode, and may be commonly connected to the second power line through a first contact portion.

Abstract: A display device includes a substrate and a pixel layer disposed on the substrate. The pixel layer includes a circuit element layer having an opening. The circuit element layer includes a first semiconductor layer and a first conductive layer that includes a first scan line pattern and an emission control line. A second conductive layer is disposed on the first conductive layer and includes a first initialization line, a second scan line pattern and a third scan line pattern. A second semiconductor layer is disposed on the second conductive layer. A third conductive layer is disposed on the second semiconductor layer and includes fourth and fifth scan line patterns. The first initialization line includes a first portion and a second portion each extending in a first direction, and a third portion disposed therebetween. The second portion extends diagonally with respect to the first direction.
