ABSTRACT:
A liquid crystal device includes a pair of first and second opposed substrates, a ferroelectric liquid crystal filled in a space defined between both the substrates, and a thin film transistor formed on at least one of the substrates. The thin film transistor is used as a spacer between the substrates, and the spacer is bonded to the first substrate opposed to the second substrate on which the spacer is formed. In another aspect, a dummy corresponding to the thin film transistor is further provided on the substrate on which the thin film transistor is formed, wherein the dummy is used as a spacer.
