Abstract: PURPOSE: To provide a smart pixel having electric signal processing and state setting functions by adding a prescribed electronic circuit, which is cooperated with a chiral smectic liquid crystal optical modulator, to this optical modulator on a semiconductor substrate. CONSTITUTION: Chiral smectic liquid crystal optical modulators 10 to 12 are formed on a semiconductor substrate 1, and a storage register 13 and a switch resistance network (or a digital/analog converter DAC) 14 which are cooperated with them are formed in the vicinity of them, and a liquid crystal driving signal is applied to the network 14, and these electronic circuits 13 and 14 are formed by a silicon VLSI technique. Smart pixels made locally intelligent in this manner are arranged as prescribed to form a circuit, and an input optical signal and an electric signal are inputted to this circuit, and prescribed optical logical operation or the like is performed, thereby realizing a composite of circuits in the highest level different from conventional.
