Abstract
A liquid crystal device of the present invention has a pair of liquid crystal substrates opposed to each other. A plurality of signal electrodes are formed on the inner surface of one of the paired liquid crystal substrates. Two scanning electrodes are formed on the inner suface of the other paired liquid crystal substrates. A liquid crystal material is interposed between the substrates. The liquid crystal material, signal electrodes and scanning electrodes form liquid crystal light shutters. The liquid crystal material is sealed only in a liquid crystal shutter section where the shutters are formed, so as to reduce capacitance between the signal and scanning electrodes. Materials which have a small dielectric constant are sealed in an area where the shutters are not formed between the signal and scanning electrodes.
