Abstract
A display device includes a first common charge transport layer, a first light-emitting layer and a second light-emitting layer each of which is formed on the first common charge transport layer, a common electrode formed over both of the first light-emitting layer and the second light-emitting layer, and a leakage blocking layer having an insulating property, the leakage blocking layer being superimposed on two adjacent end portions of the first light-emitting layer and the second light-emitting layer in plan view, and a distance between the first common charge transport layer and the common electrode is larger in a first region where each of the first light-emitting layer and the second light-emitting layer is superimposed on the leakage blocking layer than in a second region where each of the first light-emitting layer and the second light-emitting layer is not superimposed on the leakage blocking layer.
