Abstract: A display panel can include a substrate, a light-emitting element including an emission region on the substrate, a reference voltage line adjacent to the light-emitting element, and a branch line connected to the reference voltage line to apply a reference voltage to light-emitting element. The light-emitting element can emit light on the emission region in a direction of the substrate. Further, the branch line can include a semiconductor layer, and the semiconductor layer of the branch line can overlap the emission region.

Abstract: The present disclosure relates to a display panel and a repair method thereof. The display panel includes a plurality of pixel circuits in which an emission region, through which light from a light-emitting element is emitted, is defined, a power line configured to apply a pixel driving voltage to the pixel circuits, a reference voltage line to which a reference voltage lower than the pixel driving voltage is applied, and a branch line connected to the reference voltage line to apply the reference voltage to one or more of the pixel circuits. At least a portion of the branch line includes a partially metalized semiconductor layer.
