Electro-optic device, drive substrate for electro-optic device and method of manufacturing the same

An electro-optic device comprising a display unit and a peripheral drive circuit unit disposed on a first substrate, a second substrate facing said first substrate, a predetermined optical material interposed between said first substrate and said second substrate, said display unit having a pixel electrode, said device comprising:

• a gate comprising a gate electrode and gate insulation film formed on a surface of said first substrate facing said second substrate,
• a substance layer of a substance having good lattice compatibility with monocrystalline silicon formed over said gate insulation film, and
• a layer of monocrystalline silicon formed over said substance layer,
• wherein a dual gate first thin film transistor comprising said monocrystalline silicon layer as channel region, source region and drain region, and having said gate respectively in both an upper and lower part of said channel region, forms at least part of said peripheral drive circuit unit.
