Abstract
A display panel and a mask plate are provided. The display panel includes a base substrate, a thin film transistor substrate disposed on the base substrate, a light-emitting layer disposed on the thin film transistor substrate, a cathode layer disposed on the light-emitting layer, a covering layer and a protective layer laminated on the cathode layer, and an encapsulation layer disposed on the protective layer. Wherein, the cathode layer is provided with a through hole penetrating the cathode layer, and the through hole is filled with a transparent layer.
