Abstract
The invention relates to a large area organic light emitting diode display having a uniformed luminescence throughout the display area. The invention suggests an organic light emitting diode display comprising a thin film transistor substrate including a thin film transistor, a driving current line to supply an electric signal to the thin film transistor, a driving line contact hole to expose some portions of the driving current line, and an organic light emitting diode connected to the thin film transistor; a cap including a cap substrate and an auxiliary electrode disposed on a surface of the cap substrate with an area that is at least ⅓ of an area of the cap substrate; a conductive sealing material to electrically connect the auxiliary electrode and the driving current line through the driving line contact hole; and an organic adhesive joining the thin film transistor substrate and the cap.
