1. A display panel, comprising:
a flexible substrate including a display region and a peripheral region, the peripheral region being positioned in a periphery of the display region;
a plurality of self-luminescent elements provided on a first main face of the display region of the flexible substrate;
a plurality of thin film transistor (TFT) circuits provided between the first main face and the plurality of self-luminescent elements, the plurality of TFT circuits driving the plurality of self-luminescent elements;
a first inorganic film provided between the plurality of TFT circuits and the plurality of self-luminescent elements, and including a step portion which is a thinned portion of the first inorganic film and disposed in the peripheral region of the flexible substrate;
a second inorganic film covering the plurality of self-luminescent elements; and
a resin layer overlapping the second inorganic film and overlapping at least a portion of the first inorganic film in contact with an end portion of the second inorganic film.
