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.
