Display module

A display module comprising:

• A substrate including a plurality of pixels, a data line that supplies a data signal to the pixel, and a current supply line that supplies electric current to the pixel;
• wherein the plurality of pixels are arranged in a display area of the substrate,
• the current supply line is connected to a current supply bus line outside of the display area;
• wherein each of the plurality of pixels include a light emitting device, a first thin film transistor connected to the data signal line that supplies the data signal, 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 light emitting device includes a first electrode layer connected to the second thin film transistor, an organic layer formed on the first electrode layer, and a second electrode layer formed on the organic layer;
• wherein a third electrode layer is disposed on a layer at a level which is lower than a level of the second electrode layer, and is connected to the second electrode layer;
• wherein the third electrode layer is positioned outside of the current supply bus line closer to an edge of the substrate than the current supply bus line;
• and
• a terminal pad is positioned between the third electrode layer and the edge of the substrate, the terminal pad being coupled to the third electrode layer.
