Abstract

A liquid crystal display device includes a pair of opposing substrates, a liquid crystal film sandwiched between the opposing substrates, plural electrodes of a first kind disposed on an inner surface of one of the opposing substrates for defining plurality pixels, at least one electrode of a second kind disposed on an inner surface of one of (1) the one of the pair of opposing substrates so as to be adjacent to, but spaced from the plural electrodes of the first kind and (2) another of the opposing substrates so as to face the plural electrodes of the first kind, and at least one spacer disposed approximately at a center of at least one of the plural pixels for establishing a spacing between the opposing substrates. The at least one spacer is fixed to one of the opposing substrates and covered with one of (1) a corresponding one of the plural electrodes of the first kind and (2) a corresponding one of the at least one electrode of the second kind.
