1. A wiring structure comprising:

  • a substrate;

    a first conductive layer formed on a first portion of said substrate;

    a first insulative layer formed on a second portion of said substrate and on said first conductive layer;

    a second conductive layer formed on a first portion of said first insulative layer;

    a second insulative layer formed on said second conductive layer and on a second portion of said first insulative layer overlying said first conductive layer;

    an indium tin oxide layer formed on said second insulative layer,wherein a first contact hole is provided through said first and second insulative layers to expose part of said first conductive layer and a second contact hole is provided through said second insulative layer to expose part of said second conductive layer, said indium tin oxide layer extends through said first and second contact holes to electrically connect said first conductive layer with said second conductive layer, andwherein one of said first and second conductive layers is connected to one of a plurality of terminals of a thin film transistor.
