Abstract
A light emitting element and display device are disclosed. In one example, a light emitting element includes a first electrode formed on a base body. A first insulation layer is formed on the base body and the first electrode and has an aperture portion in which a part of the first electrode is exposed. A second insulation layer is formed on the first insulation layer and has a protruding end portion protruding from the aperture portion. A third insulation layer is formed on the second insulation layer and has an end portion recessed from the protruding end portion. A charge injection/transport layer is formed over the second insulation layer and the third insulation layer. An organic layer includes a light emitting layer, and a second electrode formed on the organic layer. At least a part of the charge injection/transport layer is discontinuous at the protruding end portion.
