PURPOSE:To reduce a manufacturing cost and improve the yield by forming part of peripheral circuits connected with matrix wiring to be a TFT of a complementary constitution, and composing the other part of a semiconductor chip. CONSTITUTION:For a liquid crystal device of an mXn circuit constitution, an analogue switch array circuit part 1 only of peripheral circuits connected with X-direction wiring is formed to be a thin film transistor (TFT) as well as an active element provided at an image element 6. For a part of peripheral circuits connected with Y-direction wiring also, an analogue switch array circuit part 2 only is formed to be a TFT, and the other part of the peripheral circuits is connected with a substrate by a COG method at an IC 4. The peripheral circuit part formed to be the TFT is of a complementary constitution as well as the active element provided at the image element. It is not that the whole parts of the peripheral circuits are not formed to be TFT's, but that a part of a simple element structure, a functional part of a smaller element number, and an IC part of a high cost only are formed to be TFT's. |
