Liquid crystal display device and electronic apparatus using the same and manufacturing method thereof

A liquid crystal display device of a lateral electric field mode comprising:

• a liquid crystal layer sandwiched between a first substrate and a second substrate;
• an array of pixels arranged two-dimensionally on said first substrate in a matrix pattern by crossing a plurality of video signal lines and a plurality of scanning signal lines with each other, each of said pixels being provided with at least a switching element;
• a transparent insulating film provided on said video signal lines and said scanning signal lines;
• a plurality of pixel electrodes provided on said transparent insulating film;
• a plurality of common electrodes provided on said transparent insulating film;
• and
• a plurality of common lines provided on said transparent insulating film,
• wherein said common lines being formed in a grid-shaped pattern overlap with said plurality of video signal lines and said plurality of scanning lines on said first substrate;
• wherein the common lines include (i) a first set of substantially parallel lines made of a first conductor having a metal layer and (ii) a second set of substantially parallel lines made of a second conductor having an oxide layer, the oxide layer being of a lower reflectivity against optical light than that of the metal layer, the first set of substantially parallel lines being substantially perpendicular to and crossing the second set of substantially parallel lines.
