To provide an organic light-emitting device capable of reducing a production cost by preventing moisture and oxygen from invading the organic light-emitting device, and also by eliminating unevenness formed by TFTs and signal wiring, foreign substances deposited at an end portion of an organic protective layer, and defects caused by cracks or the like of a ground.

The organic light-emitting device is provided with a second organic planarized layer 15 on a substrate 1, separated from a first organic planarized layer 5 provided with a pixel area 20, wherein on at least a region 8 between the first organic planarized layer 5 and the second organic planarized layer 15, and the second organic planarized layer 15, there is provided a protective member including at least a first inorganic protective layer 12, an organic protective layer 13, a second inorganic protective layer 14, and wherein the first inorganic protective layer 12 and the second inorganic protective layer 14 come into contact with each other above the second organic planarized layer 15.
