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.
