Abstract: A display panel and a display device configured to enhance color gamut is provided. A display device includes an auxiliary layer on at least one of the first to third anode electrodes and extending to a portion of an upper surface of an overcoat layer. The device includes a bank on the auxiliary layer and the first to third anode electrodes and including an opening exposing a portion of an upper surface of each of the first to third anode electrodes. The device includes a cathode electrode disposed on the organic layer. The overcoat layer includes a stepped portion in an area where the bank does not overlap at least one of the first to third anode electrodes and the auxiliary layer and the upper surface of the overcoat layer and a rear surface of the bank are spaced apart from each other.
