1. A self-luminous display panel comprising:
a substrate;
auxiliary wiring disposed on the substrate;
pixel electrodes disposed in a matrix of rows and columns above the substrate with defined gaps between the pixel electrodes;
light emitting layers disposed above the pixel electrodes;
a functional layer disposed above the light emitting layers, the functional layer being continuous across the light emitting layers; and
a common electrode disposed above the functional layer, the common electrode being continuous across the functional layer, wherein
the auxiliary wiring extends in plane directions of a main surface of the substrate below a first part of the pixel electrodes
above the substrate, connection areas exist where the pixel electrodes are not present, in which the common electrode and the auxiliary wiring are electrically connected to each other, and
in plan view, portions of outer edges of the pixel electrodes facing outer edges of the connection areas are recessed inwards of the pixel electrodes,
wherein in a first portion, the outer edge of the pixel electrode is recessed inward, and the first portion overlaps with the auxiliary wiring, which forms a self-luminous region due to the light-emitting layer above the pixel electrode.
