Large area organic light emitting diode display

Abstract

A large area organic light emitting diode display is provided. The organic light emitting diode display comprises a substrate including a display area defining a plurality of pixel areas in a matrix manner and a non-display area surrounding the display area; a thin film transistor disposed in each pixel area; an auxiliary cathode electrode disposed at the same layer with an element of the thin film transistor; a planar layer on the thin film transistor and the auxiliary cathode electrode; an anode electrode connected to the thin film transistor and disposed in each pixel area on the planar layer; an organic light emission layer disposed on the anode electrode; a cathode electrode covering the whole surface of the display area on the organic light emission layer; and a protective electrode covering the auxiliary cathode electrode exposed through a cathode contact hole and contacting the cathode electrode.
