1. A substrate for a liquid crystal devices comprising:

  • a plurality of data lines formed on the substrate;

    a plurality of scan lines crossing the plurality of data lines;

    a plurality of thin film transistors connected to the plurality of data lines and the plurality of scan lines;

    a plurality of pixel electrodes connected to the plurality of thin film transistors;

    a first light shielding film extending along the scan lines, formed at least below a channel region of the thin film transistors, and below junctions between the channel region and a source region and between the channel region and a drain region of the thin film transistors; and

    a second light shielding film formed above the channel region and the junctions between the channel region and the source region and between the channel region and the drain region, a width of the second light shielding film being more than a width of the first light shielding film.
