Patent ID: 8760611

Claim:
A display device comprising: a substrate; an interlayer insulation film on the substrate; a plurality of upper-layer lines which are arranged parallel to each other on an exposed top surface of the interlayer insulation film so that the plurality of upper-layer lines have exposed upper surfaces which are not covered; a plurality of lower-layer lines which are arranged on a bottom surface of the interlayer insulation film and between or adjacent to the plurality of upper-layer lines, the bottom surface of the interlayer insulation film being an opposite surface of the interlayer insulation film with respect to the exposed top surface of the interlayer insulation film; and a plurality of adjustment layers for adjusting a height of the plurality of upper-layer lines; wherein the plurality of adjustment layers are arranged on the bottom surface of the interlayer insulation film, below the plurality of upper-layer lines so as to raise an entirety of the exposed upper surfaces of the plurality of upper-layer lines to a highest position on the substrate as compared with all upper surfaces of the plurality of lower-layer lines, any portion of the exposed top surface of the interlayer insulation film and all upper surfaces of the plurality of adjustment layers; wherein the plurality of upper-layer lines, the plurality of lower-layer lines and the plurality of adjustment layers are in a partial region of the substrate outside a display region of the substrate.
