Abstract:
1. A display module comprising: a substrate, the substrate comprising: a plurality of pixels, a data line that supplies an image signal, a current supply line that supplies electric current to the pixel, a data driving circuit that supplies a data signal to the data line thereon, and a gate driving circuit; wherein the plurality of pixels comprise a display area and the pixel comprises an emitting device, a first thin film transistor connected to the data line, a second thin film transistor connected to the current supply line, and a capacitor storing an image signal and regulating a gate voltage of the second thin film transistor; wherein the emitting device comprises a first electrode layer connected to the second thin film transistor and electric current being supplied from the current supply line, an organic layer formed on the first electrode layer, and a second electrode layer serving as a cathode formed on the organic emitting layer; wherein the second electrode layer is formed to be a uniform film being common to the plurality of pixels in a display area, and a third electrode layer covered by a passivation film is disposed on a lower than the second electrode layer, wherein the second electrode layer and the third electrode layer are connected to each other outside of the display area through a plurality of contact holes formed in the passivation film.
