An electro-optical device and a method for manufacturing the same are
disclosed. The device comprises a pair of substrates and an
electro-optical modulating layer (e.g. a liquid crystal layer having
sandwiched therebetween, said pair of substrates consisting of a first
substrate having provided thereon a plurality of gate wires, a plurality
of source (drain) wires, and a pixel matrix comprising thin film
transistors, and a second substrate facing the first substrate, wherein,
among the peripheral circuits having established on the first substrate
and being connected to the matrix wirings for the X direction and the Y
direction, only a part of said peripheral circuits is constructed from
thin film semiconductor devices fabricated by the same process utilized
for an active device, and the rest of the peripheral circuits is
constructed from semiconductor chips. The liquid crystal display device
according to the present invention is characterized by that the
peripheral circuits are not wholly fabricated into thin film transistors,
but only those portions having a simple device structure, or those
composed of a small number of devices, or those comprising an IC not
easily available commercially, or those comprising an expensive
integrated circuit, are fabricated by thin film transistors. According to
the present invention, an electro-optical device is provided at an
increased production yield with a reduced production cost.
