Abstract: A display unit includes a first substrate, a transistor, first and second wiring layers, and an insulating film. The first substrate is provided with a display region and a peripheral region. The transistor is provided in the display region, and includes a semiconductor layer, a gate electrode facing the semiconductor layer, a gate insulating film between the gate electrode and the semiconductor layer, and a source-drain electrode electrically coupled to the semiconductor layer. The first wiring layer is provided in the peripheral region, electrically coupled to the transistor, and disposed closer to the first substrate than the same layer as the gate electrode and the source-drain electrode. The second wiring layer is provided on the first substrate and has an electric potential different from the first wiring layer. The insulating film is provided between the second wiring layer and the first wiring layer.

Abstract: A display device includes a display region, an organic insulating layer, a display element, and a moisture-ingress barrier. The organic insulating layer has a groove outside the display region. The organic insulating layer extends over the display region and a region outside the groove. The display element is disposed in the display region and includes, in order, a first electrode, an organic layer, and a second electrode. The organic layer includes one or more moisture-reacting layers. The moisture-ingress barrier is disposed in the groove of the organic insulating layer, includes a material identical to the material of the one or more moisture-reacting layers, and has a thickness greater than the thickness of the one or more moisture-reacting layers.
