Patent ID: 8169427

Claim:
A display module comprising: a substrate; the substrate comprising: a plurality of pixels, a signal line that supplies a data signal to a pixel, a current supply line that supplies electric current to the pixel, and a data driving circuit that supplies a data signal to the data line thereon; wherein the plurality of pixels comprise a display area of the substrate and the pixel comprises an emitting device, a first thin transistor connected to the signal line that supplies the data signal; wherein a second thin film transistor is connected to the current supply line, and a capacitor regulating a gate voltage of the second thin film transistor; wherein the emitting device comprises a first electrode layer connected to a source of the second thin film transistor, an organic emitting layer formed on the first electrode layer, and a second electrode layer formed on the organic emitting layer; wherein a third electrode layer covered by a passivation film is disposed outside of the display area and inside of a sealing area and on a lower layer than the second electrode layer; wherein the second electrode layer is connected to the third electrode layer through a contact hole formed in the passivation film; and wherein a first terminal pad is connected to the data driving circuit, a second terminal pad is connected to a scan driving circuit, a third terminal pad is connected to the current supplying line, and a fourth terminal pad is connected to the third electrode layer the first to fourth terminal pads being disposed outside of the display area of the substrate; wherein the first terminal pad, the second terminal pad, the third terminal pad, the fourth terminal pad, and the third electrode layer are formed on the same layer, respectively.
