DISPLAY PANEL AND DISPLAY DEVICE

A display panel for a display device includes a substrate, a light blocking layer disposed over the substrate, a signal line disposed over the substrate, overlapping with a portion of the light blocking layer, and having at least one branched portion, at least one protection pattern overlapping with a portion of the branched portion of the signal line, a pixel electrode disposed over the protection pattern, a light emitting layer disposed over the pixel electrode, and a common electrode disposed over the light emitting layer, wherein the branched portion of the signal line includes an area not overlapping with the light blocking layer, and wherein in the area not overlapping with the light blocking layer, the branched portion overlaps with the protection pattern, thereby preventing damage to the electrodes of the light emitting element due to a laser beam during the repair of the signal line.
