Abstract:
1. A method for manufacturing a display device, comprising the steps of: forming a first insulating layer over a transistor; forming a first electrode electrically connected to the transistor over the first insulating layer; forming a second insulating layer over the first electrode with an oxide layer interposed therebetween; etching the second insulating layer, the oxide layer and the first electrode so that the first electrode has a first region and a second region; forming a layer comprising an organic material over the first electrode and the second insulating layer; and forming a second electrode over the layer comprising the organic material, wherein the layer comprising an organic material is capable of emit light, wherein a side surface of the oxide layer is in contact with the second insulating layer, wherein the first region of the first electrode is covered by the oxide layer and the second insulating layer, wherein the second region of the first electrode is exposed from the oxide layer and the second insulating layer, and wherein a thickness of the first region of the first electrode is larger than a thickness of the second region of the first electrode.
