Abstract: According to an aspect of the present disclosure, a display device includes a first substrate including an active area and a non-active area adjacent the active area; a plurality of light emitting diodes in the active area of the first substrate; a first electrode and a second electrode in the non-active area of the first substrate and spaced apart from each other; a plurality of structures between the first electrode and the second electrode and spaced apart from each other; and a connection layer on the plurality of structures and electrically connecting the first electrode and the second electrode.

Abstract: An electroluminescent display device according to an example embodiment of the present disclosure may include a substrate including an active area having an emission area and a non-active area, a planarization layer disposed on the substrate, a light emitting element disposed on the planarization layer, a buffer layer disposed on the light emitting element and having a plurality of holes in a surface thereof and a hydrogen trap layer disposed on the buffer layer. As a result, by preventing hydrogen inflow into an oxide thin film transistor, characteristics and reliability of the thin film transistor can be improved.
