Abstract:
1. A display device comprising: a substrate; a thin film transistor formed over the substrate; an interlayer insulating film formed over the thin film transistor, the interlayer insulating film having an opening; a conductive pillar in the opening of the interlayer insulating film wherein the conductive pillar is in electrical contact with the thin film transistor; a first conductive layer formed over the interlayer insulating film wherein the first conductive layer is in direct contact with an upper surface of the conductive pillar; and a second transparent conductive layer formed over the first conductive layer wherein the second transparent conductive layer is in direct contact with the first conductive layer,. wherein a size of the opening at a portion close to the substrate is larger than a size of the opening at a portion distant from the substrate.
