Organic electroluminescence display panel and manufacturing method

A organic EL display panel and similar are provided so as to constrain a gradual increase in contact resistance between a common electrode and a power supply layer. In a panel including a substrate, a pixel electrode, a power supply layer formed with separation from the pixel electrode, a resin partition layer having an aperture over the power supply layer and over the pixel electrode, an organic light-emitting layer, a functional layer in contact with the organic light-emitting layer in the aperture and electrically connected to the power supply layer, and a common electrode, an inorganic film is disposed between the functional layer and side walls of an opening for the aperture over the power supply layer in the resin partition layer.
