A display device that lends itself to easy repair of a defective pixel is presented. The device includes: a thin film transistor formed having a first electrode and a second electrode, the second electrode having a first part facing the first electrode, a second part that protrudes from the first part and having a first width, and a third part that extends from the second part and having a second width which is different from the first width. The device also includes a wall encompassing the pixel electrode and a common electrode formed on the wall.In one version of the repairing process, the second part of the second electrode is coupled to the common electrode. This coupling causes electric current from the second electrode to flow to the common electrode instead of to a light emitting diode, thereby converting a white spot to a black spot.
