Liquid crystal display contact structure having conducting spacers and plural conducting films

A contact structure of an electro-optical device comprising:

• a first conducting film formed over a first substrate;
• a first dielectric film covering at least a portion of said first conducting film and having an opening portion to expose a portion of said first conducting film;
• at least one second dielectric film formed on said first conducting film, thereby remaining parts of said opening portion;
• a second conducting film covering said first and second dielectric films and said parts of said opening portion;
• a third conducting film formed under a second substrate opposite to said first substrate;
• and
• a plurality of conducting spacers held between said first and second substrates and connecting to said second and third conducting films;
• wherein said first and second conducting films are connected at said parts of said opening portion, and
• wherein said second conducting film, said conducting spacers and said third conducting film are connected in turn on said second dielectric film, wherein said conducting spacers maintain a gap between said first and second substrates.

A contact structure of an electro-optical device comprising:
