1. A display device, comprising:

  • a thin film transistor formed on a substrate, said thin film transistor having source, drain and channel regions and a gate electrode adjacent to said channel region with a gate insulating film between said gate electrode and said channel region;

    a gate line electrically connected to said gate electrode and configured to extend in a first direction on said substrate;

    a first interlayer insulating film formed over said thin film transistor and said gate line;

    a source line formed on said first interlayer insulating film and electrically connected to the source region of said transistor through a first contact hole of said first interlayer insulating film, wherein said source line extends in a second direction substantially orthogonal to said gate line to define a pixel region;

    a second interlayer insulating film formed on said first interlayer insulating film and said source line;

    a light shielding layer formed on said second interlayer insulating film to shield at least said source line and said gate line;

    a drain electrode formed on said second interlayer insulating film and electrically connected to said drain region of said transistor through a second contact hole formed in said first and second interlayer insulating films;

    a third interlayer insulating film formed on said second interlayer insulating film and said light shielding layer; and

    a pixel electrode formed on said third interlayer insulating film and electrically connected to said drain electrode through a third contact hole formed in said third interlayer insulating film,wherein a part of said light shielding layer overlaps with a periphery of said pixel electrode with said third interlayer insulating film interposed between said light shielding layer and said pixel electrode to form a storage capacitor.
