Abstract: A display panel includes a flexible substrate. The flexible substrate includes a display region and a peripheral region. A plurality of self-luminescent elements is on a first main face of the display region of the flexible substrate. A plurality of thin film transistor (TFT) circuits is between the first main face and the self-luminescent elements. The TFT circuits drive the self-luminescent elements. A first inorganic film is between the TFT circuits and the self-luminescent elements, and includes a step portion which is a thinned portion of the first inorganic film disposed in the peripheral region of the flexible substrate. A second inorganic film covers the self-luminescent elements. A resin layer overlaps the second inorganic film and overlaps at least a portion of the first inorganic film in contact with an end portion of the second inorganic film.
