1. A liquid crystal device for an electro-optical device, the liquid crystal device including a plurality of liquid crystal cells wherein data signals are supplied to the liquid crystal cells through a plurality of field effect transistors arranged in a plurality of picture elements, the liquid crystal device comprising:

  • a substrate having a pixel region and at least one driver region, said picture elements being arranged in said pixel region;

    driving means formed in the at least one driver region for driving said field effect transistors, the driving means including at least a shift register having CMOS thin film transistors; and

    a passivation film having a thickness of at least about 1 μ

    m formed on the driver region and not formed on the pixel region, the passivation film forming a waterproof layer protecting the driver region from the external environment.
