摘要： A display device includes a substrate including a display area and a non-display area; pixels disposed in the display area and including respective light emitting units; a first conductive pattern disposed between the pixels; and a power source line disposed in the non-display area and electrically connected to the first conductive pattern. Each of the light emitting units includes a light emitting element, a first pixel electrode disposed on a first end of the light emitting element, and a second pixel electrode disposed on a second end of the light emitting element. The first conductive pattern and the second pixel electrode are disposed on a same layer.
